Nebulae are clouds of gas and dust in space. There are several types including dark nebulae which appear black, reflection nebulae which glow blue from reflected starlight, and emission nebulae which glow in specific colors due to ionized gas. Quasars are extremely bright active galactic nuclei containing supermassive black holes. The first quasar, 3C 273, was discovered in the 1960s and found to be billions of light years away. Blazars are a type of quasar that emit most of their energy as gamma rays and X-rays. Quasars can be thousands of times brighter than entire galaxies and contain disks of superhot gas and jets of matter near supermassive black holes.

Quasars are the most luminous and energetic objects in the universe. They are formed when matter falls into supermassive black holes at the centers of galaxies, releasing enormous amounts of energy. Quasars can outshine entire galaxies and their luminosity can vary over time. They serve as reference points for establishing the international celestial reference system due to their brightness, small size, and distant locations throughout the universe.
Galaxies. Quasars. lecture notes chapter 20
Galaxies often interact and collide due to their close proximity. Collisions trigger intense bursts of star formation and can destroy spiral arms. Over time, collisions and mergers drive the evolution of galaxies, with giant elliptical galaxies forming from the merging of many smaller galaxies through a process called galactic cannibalism. Active galactic nuclei are powered by accretion disks around supermassive black holes, and phenomena such as jets, lobes, and broad emission lines provide evidence of black holes at the centers of galaxies.
black hole
1) A black hole is a region of space where gravity is so strong that nothing, not even light, can escape its pull. They are formed when a large star runs out of fuel and collapses in on itself due to gravity.
2) There are three main types of black holes: stellar black holes formed by collapsed stars, supermassive black holes found at the center of galaxies that are millions of times the mass of the sun, and theoretical tiny "pinpoint" black holes.
3) When a massive star runs out of nuclear fuel, its stability fails under its own intense gravity, causing its radius to shrink within its Schwarzschild radius and forming a black hole as its outer layers explode
Astrophysics Presentation
This document discusses several topics in astrophysics including the solar system, meteors and comets, black holes, time travel, and extraterrestrial life. It provides definitions and key facts about these subjects such as meteoroids becoming meteors upon entering Earth's atmosphere, black holes having no surface and stretching objects that fall into them, the possibility of time travel causing paradoxes, and evidence that extraterrestrial life could exist but has not been proven. The document also shares some additional interesting astronomical facts and comparisons.
Solar System
The document provides an overview of Earth's atmosphere and how it protects the planet, as well as examples of meteor impacts on Earth and their effects. It then discusses observations of other planets like Mars, Venus, Jupiter, and beyond, noting features of their atmospheres, moons, and other characteristics. The document concludes by mentioning the Kuiper Belt and discovery of thousands of small bodies orbiting beyond Neptune's orbit.

The document discusses the evolution and deaths of stars. It describes how low-mass stars like the Sun will evolve into red giants and planetary nebulae over billions of years. More massive stars may explode as supernovae, producing neutron stars or black holes and spreading heavy elements throughout space. Neutron stars can be observed as pulsars that emit beams of radiation. The origins of elements on Earth and phenomena like cosmic rays and pulsars are also examined.
The life of stars
Nebulae are clouds of gas and dust in space that serve as the birthplaces of stars. There are several types of nebulae including emission nebulae, reflection nebulae, and dark nebulae. Stars are born from nebulae and progress through different stages in their life cycles. A star will evolve from its birth in a nebula as a red dwarf or giant, through a white dwarf phase, and eventually end its life as a black dwarf, supernova, or black hole.
Black Holes
Black holes are areas of extremely dense mass that have such strong gravitational pull that not even light can escape. They are formed when giant stars collapse at the end of their life cycles. Black holes can range significantly in size, from around 6 miles across to larger than our entire solar system. Scientists identify black holes by observing the orbits and emissions of objects near them, like stars and gas, using instruments that detect x-rays, radio waves, and other forms of light.

The Black Hole In Science And Quran Ver1
The document discusses black holes and how they are described in both science and the Quran. It provides 3 key points:
(1) The Quran mentions black holes over 1400 years ago using specific characteristics - that they are invisible, rotating rapidly, and sweep up everything around them.
(2) Modern science has only recently discovered black holes, in 1969, and describes them using these same characteristics.
(3) A non-Muslim astronomer also used these same words to describe black holes without having read the Quran, showing its divine origin.
Black hole
Black holes are regions of space where gravity is so strong that not even light can escape. They form when massive stars collapse at the end of their life cycles. Black holes can be stellar-mass, weighing around 10 times the mass of our Sun, or supermassive - containing millions to billions of solar masses at the centers of galaxies. Although black holes themselves are invisible, astronomers can detect them through their interaction with nearby stars and gas.
Black holes
Black holes are regions of space where gravity is so strong that nothing, not even light, can escape. They form when large stars collapse at the end of their life cycles, compressing their mass into a tiny space. There are several types of black holes including stellar black holes formed by collapsed stars and supermassive black holes found at the center of galaxies containing billions of solar masses. If matter enters a black hole's event horizon, it becomes "spaghettified" as tidal forces stretch and compress it due to the extreme warping of spacetime.
Black holes
Black holes are regions of spacetime where gravity is so strong that nothing, not even light, can escape. They are defined by an event horizon surrounding a singularity of unknown composition. There are three main types - stellar black holes formed by collapsed stars, supermassive black holes found at the center of galaxies, and primordial black holes theorized to have formed in the early universe. Black holes vary greatly in size from 10 to 100 solar masses for stellar black holes up to billions of solar masses for supermassive black holes located in galaxies.
Black Holes
This document provides information about black holes, including their structure, formation theories, detection methods, and two specific black holes - Sagittarius A* and Cygnus X-1. It describes the key components of black holes as the singularity at the center with infinite density, the event horizon boundary, and accretion disks of spiraling material. It also discusses theories such as black holes forming from collapsed stars and acting as tunnels to other universes. Sagittarius A* is identified as the supermassive black hole at the center of the Milky Way, while Cygnus X-1 was the first galactic black hole candidate discovered.
Bright quasar 3c273
3C 273 was one of the first quasars discovered in 1963. It remains one of the brightest and best studied quasars. It is located approximately 3 billion light years from Earth and radiates energy equivalent to 1014 times the luminosity of the Sun. 3C 273 plays a key role in understanding the nature of quasars as powered by accretion disks around supermassive black holes. It continues to be intensely observed across the electromagnetic spectrum to better understand the physics occurring in these energetic and distant cosmic objects.

Black hole is very interesting topic. think about this topic because our scientists work on this for us.
Black Holes and its Effects
1. Black holes are regions of space where gravity is so strong that nothing, not even light, can escape. They form when massive stars collapse at the end of their life cycles.
2. There are two main types of black holes - static and rotating. The rotating type, known as Kerr black holes, form when collapsed stars have angular momentum.
3. As a star collapses, it passes through stages as a red giant, white dwarf, and neutron star until its mass exceeds around 3 solar masses, causing it to collapse entirely into a black hole with a singularity at its center.

There are several types of black holes including stellar black holes formed by collapsed stars and supermassive black holes millions to billions times the mass of our sun. As objects fall into a black hole's event horizon, they become "spaghettified" as the black hole's immense gravity stretches and pulls them apart.

BLACK HOLES
1) Black holes were first theorized in 1783 and were described by Einstein's theory of general relativity in 1916. The term "black hole" was coined in 1967.
2) Black holes are regions of space where gravity is so strong that not even light can escape. They form when massive stars collapse at the end of their life cycles.
3) There are three main types of black holes - stellar black holes resulting from collapsed stars, supermassive black holes at the centers of galaxies, and theoretical micro black holes. Black holes cannot be seen directly but their effects on nearby stars and gas provide evidence of their existence.
Year 4 Space by Jordan V
1) Black holes are regions where gravity is so strong that nothing, not even light, can escape and they are formed by the collapse of massive stars at the end of their life cycles.
2) Very massive stars end their lives in huge explosions that blow away the outer parts of the star, leaving behind a very dense core that collapses into a black hole.
3) At the center of a black hole is a singularity, a point where all the dust and gases from the collapsed star swirl around at near light speed due to the extreme gravitational pull.
Black holes
This document discusses black holes. It begins with a brief history of ideas about black holes from the 18th century to modern times. It then describes how black holes form from massive stars undergoing gravitational collapse at the end of their life cycles. It outlines the key characteristics of black holes, including their structures consisting of singularities surrounded by event horizons. The document also notes that black holes can continue growing by absorbing matter and merging with other objects. In conclusion, it states that while there is no limit to the size of black holes, the largest are likely in the centers of galaxies and contain billions of solar masses.
Blackhole
A black hole is a region of spacetime where the gravitational pull is so strong that nothing, not even light, can escape. The boundary of this region is called the event horizon. Black holes form when very massive stars collapse at the end of their life cycle. Supermassive black holes millions of times the mass of our sun may form at the centers of galaxies by absorbing other stars and merging with other black holes. While black holes themselves are invisible, their presence can be inferred through their interaction with surrounding matter like accretion disks and the orbits of nearby stars.
An Introduction about The Black Hole and its types
Black holes are regions of space where gravity is so strong that nothing, not even light, can escape. They form when massive stars over 8 times the sun's mass die in supernova explosions. Billions of black holes exist between galaxies and millions exist within our own Milky Way galaxy. Black holes can be detected by their gravitational effects on nearby stars and the intense light produced from material falling into supermassive black holes at galaxy cores. Orbiting black holes is possible only at precise speeds - too slow will lead to spiraling in, too fast will escape, and intermediate speeds result in complex rosetta orbits.
Black hole
Black holes are formed when massive stars collapse in on themselves and the gravity is so strong that not even light can escape. Einstein's field equations describe how mass and energy curve spacetime and can create black holes. Although black holes cannot be directly observed, evidence suggests they exist from phenomena like Hawking radiation. Hawking radiation occurs as virtual particles near the event horizon can materialize, with one particle escaping as radiation while the other falls into the black hole, causing it to slowly lose mass over time. This challenges information theory which says information should be preserved over time, creating what is known as the black hole information paradox.
Black holes presentation
Black holes are objects with extremely strong gravitational fields that do not allow anything, including light, to escape once it passes the event horizon. They are formed when very massive stars collapse at the end of their life cycles. Black holes are small but incredibly dense, with all their mass concentrated at a central singularity. If material such as gas from a nearby star falls into a black hole, it becomes heated and glows, making the black hole visible with telescopes.
Lightyear
A light year is a unit of distance used to measure large distances in space. It is defined as the distance that light travels in one year, which is about 9.46 trillion kilometers. Looking at distant objects in the universe means seeing them as they appeared in the past, since it takes time for their light to reach us - the further away an object is, the further back in time we are seeing it. The universe is estimated to be at least 156 billion light years in size.
Pulsars and black hole
Pulsars are rapidly rotating neutron stars that emit beams of electromagnetic radiation. They were discovered in 1967 and form during supernova explosions when massive stars collapse. Pulsars appear to pulse because they rotate and emit beams of radiation that sweep across space like a lighthouse, appearing brighter when facing Earth. They are very dense and spin very quickly due to their compressed gravity. Black holes form when massive stars collapse at the end of their life and have such strong gravity that not even light can escape. They come in different sizes from stellar to supermassive and are detected by their effects on nearby stars. The event horizon marks the boundary where light cannot escape from a black hole's strong gravity.
More active galaxies
- About 5-10% of large galaxies contain active galactic nuclei (AGNs) or quasars, with brighter quasars being rarer.
- AGNs and quasars are important because they are extremely bright and allow astronomers to illuminate distant material between Earth and the quasar that cannot be seen directly.
- Quasar absorption lines are usually caused by interstellar gas and dust within or surrounding a galaxy, which absorbs specific wavelengths of light from the quasar.
- The Lyman-alpha forest refers to the many absorption lines seen in quasar spectra caused by hydrogen clouds along the line of sight between Earth and the quasar. Studying these clouds helps astronomers understand the distribution of gas
Key technological advancements
The document summarizes several key technological advancements in space exploration, beginning with Sputnik 1, the first artificial satellite launched by the Soviet Union in 1957. It then discusses Sputnik 2, which carried the first animal (a dog named Laika) into space, and Explorer 1, the first U.S. satellite. Subsequent sections outline early Soviet and American manned spaceflights including Vostok, Gemini 5, and Apollo 11, which landed the first humans on the Moon. The document concludes with descriptions of the Galileo and James Webb Space Telescope missions.

Finally, it predicts that astroinformatics will be crucial for making sense of the huge volumes of data that will be produced by next-generation telescopes.
Secular Processes and Galaxy Evolution
A talk I gave on Secular (Slow) Processes and Galaxy Evolution given at the Evolutionary Paths in Galaxy Evolution (or "Galaxy Zoo") conference held in Sydney, Sept 2013. (http://www.atnf.csiro.au/research/conferences/2013/gzo/)
Stars And Galaxies
1. Stars form from nebulae, which are dusty clouds in space. They begin as protostars and then become main sequence stars like our sun or massive stars.
2. After billions of years, main sequence stars become red giants as they run out of hydrogen fuel. Massive stars become red supergiants.
3. When stars die, red giants form planetary nebulae and red supergiants explode as supernovae. The remains of stars form neutron stars, black holes, white dwarfs or black dwarfs.
life cycle of a star
The life cycle of stars depends on their mass. Lower mass stars like our Sun will eventually become red giants then white dwarfs. Higher mass stars live shorter lives and end as supernovas, leaving behind neutron stars or black holes. All stars begin as nebulae of dust and gas that collapse under gravity into protostars and main sequence stars fueled by nuclear fusion.
Cuásar o quasar
Los cuásares son objetos extremadamente brillantes ubicados a grandes distancias que emiten grandes cantidades de energía de manera similar a las estrellas pero con un desplazamiento al rojo mayor debido al efecto Doppler, indicando que se están alejando a velocidades extremadamente altas. Se cree que los cuásares contienen agujeros negros supermasivos en sus centros que atraen grandes cantidades de materia a través de discos de acreción.

Weather observations can be made by checking a thermometer, looking at cloud cover, and measuring wind speed. Meteorologists study weather data from tools like satellites and radar to create maps and improve forecasting of conditions like tornadoes and snow storms, which helps people prepare for dangerous weather and decide when to evacuate.
Space weather and potential impact on earth’s climate dec 19 10 v2
This document discusses space weather and its potential impacts on Earth's climate and seismic activity. It provides an overview of the solar system and its dynamics, as well as how our solar system interacts with the Milky Way galaxy and larger universe. Recent observations have found evidence that the outer boundaries of our solar system are being compressed as we pass through Galactic clouds, allowing more cosmic rays and energetic particles to enter the inner solar system. This could affect Earth's climate and increase seismic activity. The document also discusses changes observed on other planets in our solar system, such as the growth of dark spots on Pluto and changes in cloud cover on Mars.
Portfolio quasar
The document provides details about a student design team that is redesigning their Formula 1 race car for a national competition. It outlines the responsibilities of each team member and describes the iterative design process they went through to optimize various aspects of the car's design like the logo, uniforms, and aerodynamic components. This included testing different shapes, sizes, and materials through computer simulations and physical testing to minimize drag and improve performance. The document demonstrates how the team worked collaboratively and used an analytical approach to refine their car design.
Red quasars in the 2XMMi/SDSS-DR7 cross-correlation
The document discusses a study of red quasars found through cross-matching the 2XMMi X-ray source catalog and the SDSS-DR7 optical catalog. Optical and X-ray analyses were performed on 64 red quasar candidates. The analyses found that X-ray absorption was not reliably linked to optical obscuration. Approximately 25% of the X-ray bright red sample, or 7-9 sources, were determined to be intrinsically red quasars through their optical and UV continuum shapes. Further analysis is needed to better characterize the intrinsically red quasar population.

Dark side ofthe_universe_public_29_september_2017_nazarbayev_shrt
1) The document discusses the history of discoveries about the universe, from ancient cosmologies to modern precision cosmology. Key developments include realizing the sun is at the center of the solar system, discovering other galaxies and the expansion of the universe, and detecting the cosmic microwave background and dark matter.
2) Current open questions about the universe include the nature of dark matter and dark energy. Observations show dark energy is accelerating the expansion of the universe, but its underlying cause remains unknown. Precise measurements aim to distinguish between models of dark energy.
3) The standard cosmological model has been very successful in explaining observations but has fine-tuning problems regarding why the present epoch is dominated by both matter and dark energy.
DM(final)
- 99% of the universe is believed to be dark matter. Scientists are convinced that only 1% of the 5% of baryonic matter present in the universe can be seen.
- Evidence has accumulated that there is more matter in galaxies than what meets the eye through telescopes. As much as 90% of the matter in the universe must be in some "dark" form.
- Observations of galaxy rotation curves showed that stars at the outer edges of galaxies move at the same speed as inner stars, even though there isn't enough visible matter to account for the gravitational force needed to keep them in orbit, suggesting additional unseen "dark matter" is present.
GALAXIES
This document discusses different types of galaxies and black holes. It describes how galaxies are made up of stars, gas, and dust that orbit around a common center. Galaxies are classified as elliptical, spiral, or irregular based on their shape and structure. The document also describes three types of black holes: low-mass stellar black holes formed from collapsed stars; supermassive black holes located at the center of galaxies containing millions to billions of solar masses; and intermediate-mass black holes recently discovered. While black holes themselves are invisible, astronomers can detect them by observing their effects on nearby stars and gas through techniques like observing orbital motions and detecting X-ray emissions.
Cosmic monster' star spits energy with the force of a billion suns
High energy outbursts in this type of neutron star — a magnetar — are thought to be caused by "starquakes."
The Messier Objects Catalogue
M6, also known as the Butterfly Cluster, is an open star cluster located in the constellation Scorpius. It has a distinctive butterfly shape when viewed through binoculars or a small telescope. The cluster's measurements, including its magnitude, age, and distance estimates, have varied between studies. M6 is one of the closest Messier objects to the center of the Milky Way galaxy.
Space mysteries 3
The document discusses three mysteries: auroras, black holes and cosmic X-rays, and comets. It provides background on each mystery and notes that auroras involve distinct magnetosphere processes, black holes can be studied through polarized X-ray measurements, and comets may have brought water to Earth and studying comet material may reveal secrets about the origins of the universe.
Hubble Telescope Pictures
The document discusses the top 10 photographs taken by the Hubble Space Telescope over its 16 years in operation. It begins by providing context about the Hubble telescope and light years as a measurement of distance. It then lists and provides brief descriptions of each of the top 10 photographs, which include images of galaxies like the Sombrero Galaxy and nebulae like the Ant Nebula, Eskimo Nebula, and Hourglass Nebula.
Amazing Pictures In Space
This Hubble Space Telescope image shows the dramatic nebula M1-67 surrounding the Wolf-Rayet star WR124. Hot clumps of gas are being ejected from the star at over 100,000 miles per hour into vast arcs and filaments of glowing gas. Though previously only detected spectroscopically, Hubble can directly image gas blobs 100 billion miles wide that are each about 30 times the mass of Earth. The star is ejecting mass violently during its short and transitional phase.
400 Years Of The Telescope
This document provides summaries of 15 astronomical images in 3 sentences or less. It describes various celestial objects like galaxies, nebulae, star clusters and more. The summaries concisely highlight the key features and phenomena shown in each full-color image from NASA telescopes and observatories.
Cosmology And Astronomy
The Hubble Space Telescope is a large space-based observatory named after astronomer Edwin Hubble that has provided unprecedented views of the universe. Hubble orbits Earth every 96 minutes and has taken many famous images including pillars of creation in the Eagle Nebula and the Crab Nebula. Some of Hubble's images show planetary nebulae, star clusters, galaxies and more distant objects in the universe.
1ST-Quarter-Lesson-1to-5-Handout-Reviewer-for-Earth-and-Life-Science.pdf

2) It describes the different types of galaxies including spiral, elliptical, irregular, barred spiral, lenticular, and peculiar galaxies. It also discusses the Milky Way galaxy and solar system.
3) The Earth is described as a complex system consisting of interconnected subsystems - the biosphere, hydrosphere, atmosphere, and geosphere. The document outlines the composition and layers of the Earth's crust, mantle, and core.
Out Of This World
The document provides an overview of the universe and some of its key components:
1. The universe originated from the Big Bang around 13.7 billion years ago and has been expanding and cooling ever since.
2. Galaxies form the basic building blocks of the universe and come in three main types: spiral, elliptical, and irregular. Our galaxy is the Milky Way galaxy.
3. Stars are born in nebulae and come in different colors, temperatures, and magnitudes depending on their stage of life. When stars die, they may become black holes, neutron stars, or white dwarfs.
06 Galaxies Mc Neely
The document provides an overview of galaxies and the Milky Way galaxy. It discusses that galaxies contain billions of stars and describes our Milky Way galaxy as a spiral galaxy containing 100-200 billion stars. It also discusses other galaxy types like elliptical galaxies and active galaxies like quasars.
The Sun by Jamie Lee Corpuz (I Made)
The Sun's diameter is 864,938 miles, almost 10 times larger than Jupiter and about 109 times the size of Earth. Astronomers study the Sun using instruments to analyze variations in light and the Sun's effect on Earth's climate. Sunspots are relatively cool, dark patches that can be over 10 times the diameter of Earth and follow an 11-year cycle, with the current cycle peaking in the middle of 2000.
Astronomy
The document provides information about astronomy and the solar system. It begins by defining astronomy and describing early astronomers like Copernicus and Galileo. It then discusses concepts like the universe, galaxies, and the Milky Way galaxy. The bulk of the document is focused on defining and describing components of the solar system, including the sun, planets like Earth, Venus, and Mercury, and units like light years and astronomical units. It provides details on concepts like planetary orbits, rotations, and transits. The summary concludes with an overview of the key topics covered.
The milky way’s neighborhood
Within a few million light-years of the Milky Way are several dozen galaxies that make up the Local Group, including the Andromeda Galaxy. The Andromeda Galaxy is the largest galaxy in the Local Group and shares many similarities with the Milky Way, such as both being large spiral galaxies of roughly the same age. Other notable galaxies in the Local Group include the Large and Small Magellanic Clouds, which orbit the Milky Way.
Black holes
The document discusses black holes and their properties. It describes how John Archibald Wheeler coined the term "black hole" and how Pierre Simon Laplace first proposed the concept in 1795, calculating that an object compressed into a small enough radius would have an escape velocity greater than the speed of light. It provides details on escape velocity and the event horizon of a black hole, beyond which nothing, not even light, can escape. The document classifies different types of black holes by mass and size.
Creative kids P.P.T. Group Geography Project.pdf
1. The document provides information about various celestial bodies including galaxies, the Milky Way galaxy, Andromeda galaxy, constellations, the Solar System, planets like Mercury, Venus, Earth, Mars, Jupiter, and features like the Kuiper belt.
2. It discusses key facts about these objects such as their composition, size, and characteristics.
3. Nicolaus Copernicus is mentioned for developing the heliocentric model that placed the Sun at the center of the Solar System.
What is a black hole
Black holes are regions of space where gravity is so strong that not even light can escape. They form when very massive stars collapse at the end of their life cycles. While black holes cannot be seen directly, astronomers can detect them by observing their effects on nearby objects like stars and gas, and through detection of x-rays emitted during accretion. Black holes come in different sizes, from stellar-mass black holes up to supermassive black holes that may exist at the centers of galaxies.

The Teaching Profession
The teaching profession is challenging as teachers must make lessons meaningful and relevant to students' lives. While the curriculum is congested, teachers strive to store important information in students' long-term memory so they can appreciate the beauty of the world. The goal of meaningful learning is to make school as relevant as possible to students. However, teaching is a never-ending quest, as teachers must consider how to respond to today's needs and fill students' minds with important rather than just half of the information.
The Practice Teaching Experience
1) Practice teaching is an important but challenging part of teacher training that tests students' commitment to teaching and requires independent learning.
2) Creating effective lesson plans, particularly developing objectives and motivation, is difficult but important for engaging students.
3) Support from cooperating teachers is invaluable for learning teaching strategies and preparing for final demonstrations.
Personal and Growth Development
The author is reflecting on their experience with practice teaching, which will be ending in one week. While they view the ending as a relief, they acknowledge that the experiences have been valuable. Teaching is difficult, especially for a beginner, but the author sees it as an opportunity to take risks and learn from mistakes. The essence of life, according to the author, is to change, be inspired, and have an open dialogue. They define teaching as a career that demands continual growth, development, and learning. The motivation to improve comes from within the author and their desire to properly educate students. They seek feedback from students to evaluate their own progress.
Students Assessment, Achievement and Behavior
This journal entry discusses the author's reflections on their four remaining weeks of student teaching. It explores how student assessments, achievements, and behavior impact the author's development as a teacher. The author finds student test scores and behavior motivational, but acknowledges two months is not enough time to see changes in behavior. The author hopes being affected by students encourages further growth into a capable educator.
Strategies in Teaching
The document discusses a pre-service teacher's reflections on using various teaching strategies in their lessons. The teacher discusses struggling at first with focusing too much on content but learning the importance of strategies to engage students. Some strategies they have used successfully include Read-Think-Pair-Share, collaborative learning, jigsaw activities, games, and higher-order thinking questions. The teacher finds creating worksheets that require interpretation and problem-solving to be effective. Overall, the teacher feels teaching is a task-based and problem-based process and they still have more to learn but are making progress in using different strategies.
Classroom Management and the Teaching Learning Process
The document discusses the challenges of classroom management and effective teaching. It notes that classroom management is difficult due to noisy or off-task students. Maintaining an ideal learning environment requires managing student behavior. Engaging students and eliciting their understanding is also challenging, as students may say they don't understand or find the material complicated. Effective teaching requires adapting to student needs using a variety of skills. The success of teaching and learning depends on both processes being interlinked.
The Learning Environment and Diversity of Learners
The document discusses the author's first teaching experiences at TCSHS. It describes handling 5 different classes on their first day back from vacation, with varying levels of engagement between the higher and lower sections. The author appreciated the students' participation by asking questions. TCSHS is praised for maintaining small class sizes in well-ventilated, lighted classrooms conducive to learning. The school also advocates technology use in teaching and learning, with multimedia devices, televisions, an e-library, and good supplementary books. The diversity of learners presents a challenge to sustain student excitement, but the physical learning environment is well-supported for 21st century education.
Social Regards in Teaching and Learning
The document discusses the importance of community involvement in schools. It describes a school family day event where parents, teachers, local government, and others participated in games and activities. This showed the author that every school is a miniature community that requires collaboration between various stakeholders to succeed. The author realizes teaching is a crucial role because teachers are responsible for students' success and ability to support themselves, pay taxes, and be productive citizens. Parents must also guide their children's learning to supplement what is taught in school and help them achieve their dreams.
The Mentoring Spirit
The document discusses the author's experience with their mentor during their practice teaching. They were nervous but excited to teach at Tuguegarao City Science High School. Their mentor was known to be strict but provide good strategies. During their first meeting, the mentor gave the author a teaching method to use. The author hopes their mentor will provide an orientation, explain classroom management, and communicate gently while being willing to support the author. The author believes they will learn from any mistakes and hopes their experience will be calm under the guidance of their mentor.
Community Linkages and Voluntarism
The document discusses community linkages between schools and outside communities. It states that teachers play a key role in facilitating these connections by talking both inside and outside of school. Teachers are seen as respectable members of both the student and parent community. While teachers have high social status, they are underappreciated economically. The document also discusses the author's volunteer work during their field study placement, where they helped clean laboratories and gardens at the school and performed in a Christmas program.
Educator vs
Three sentences summarizing the document:
The document discusses the differences between teachers and educators, with teachers focusing on passing on information and ensuring it is learned correctly, while true educators draw out the intelligence and abilities within students, allowing them to develop their talents. It provides several examples of educators being able to uncover the abilities in students who had been labeled or discounted, such as unlikely students winning a speech contest. The essence of teaching is creating numerous learning moments every day through an educator's actions, experience, and creativity, though current standardized testing trends have reduced teaching to testing administration.
Field study 6 Episode 2
This document discusses educational philosophies and the author's reflections on observing a teacher. It begins by listing statements related to different educational philosophies. The author then observes a science teacher and notes that the teacher uses elements of progressivism, existentialism, perennialism, and behaviorism. Through this observation, the author gains insight into how their own educational philosophy will influence their teaching approach and ability to address diverse learners by creating a conducive learning environment.
Art of Printing: Styles and Techniques
The document discusses various print-based media and techniques, including etching, linocut, screen printing, lithography, letterpress, gravure, photocopying, laser printing, inkjet printing, desktop publishing, and 3D printing. It provides detailed descriptions and steps for different print processes like etching, linocut, screen printing and lithography. The document aims to educate about traditional and digital print media forms.
Introduction to Chemical Bonding
This document introduces chemical bonding and discusses Lewis dot representations to show valence electrons for different elements, as well as ionic and covalent bonding types. It provides examples of Lewis dot diagrams for elements with varying valence electron counts and introduces the concepts of ionic and covalent bonding.
The milky way
The Milky Way galaxy is a spiral galaxy that contains our solar system, including Earth. It is called the Milky Way because it appears as a dim glowing band of light in the night sky. The Milky Way is over 100,000 light years in diameter and Earth orbits around the Milky Way at approximately 128,000 miles per hour as part of the Milky Way's structure.
Galactic dust and clouds
The interstellar medium is the matter that exists between stars in galaxies, consisting of gas and microscopic dust particles. About 1% of a galaxy's mass is made up of interstellar medium. In the Milky Way, the density of the interstellar medium is about 1 atom per cubic centimeter, much less dense than Earth's atmosphere. Molecular clouds within the interstellar medium can be enormous, many light years across and containing thousands of times the mass of the Sun. The interstellar medium plays an important role in the formation of stars, planets and other astronomical objects.
Black holes in galaxies and active galaxies
Every galaxy contains a supermassive black hole at its center. When matter falls into the black hole rapidly, tremendous amounts of energy are released. Galaxies with actively feeding black holes at their centers are called active galactic nuclei or AGNs. The luminosity of an AGN depends mainly on the rate at which matter falls into the central supermassive black hole.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.
Phenomics assisted breeding in crop improvement
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.

Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.

The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptx
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).

Nebulae, quasars,
- 1. NEBULAE, QUASARS, AND BLAZARS Bryan Nozaleda
- 2. What is a nebula? A nebula, derived from the Latin meaning “mist,” is any cloud or collection of interstellar medium in one location in space. Nebulae are produced in many different ways.
- 3. How many kinds of nebulae are there? Generally, types of nebulae are described either by their appearance (for example, dark nebulae, reflection nebulae, and planetary nebulae) or the physical processes that create them (such as protostellar nebulae, protoplanetary nebulae, or supernova remnants).
- 4. The nebula NGC 604, located in the galaxy Messier 33, is 1,500 light- years across. (NASA, Hui Yang University of Illinois)
- 5. What are dark nebulae? Dark nebulae are, well, dark. They look like black blobs in the sky. They are generally dark because they contain mainly cold, high-density, opaque gas, as well as enough dust to quench the light from stars behind them. One example of a dark nebula is the Coal Sack Nebula, located near the constellation Crux (The Southern Cross).
- 6. What is a reflection nebula? A reflection nebula is lit by bright, nearby light sources. The dust grains in them act like countless microscopic mirrors, which reflect light from stars or other energetic objects toward Earth. To the human eye, reflection nebulae usually look bluish. This is because blue light is more effectively reflected in this way than red light.
- 7. What is an emission nebula? An emission nebula is a glowing gas cloud with a strong source of radiation—usually a bright star— within or behind it. If the source gives off enough high-energy ultraviolet radiation, some of the gas is ionized, which means the electrons and nuclei of the gas molecules become separated and fly freely through the cloud. When the free electrons recombine with the free nuclei to become atoms again, the gas gives off light of specific colors. Which colors they emit depends on the temperature, density, and composition of the gas. The Orion Nebula, for example, glows mostly green and red.
- 9. What is a quasar? The term “quasar” is short for “quasi-stellar radio source.” Subsequent studies showed that they were not stars at all, but rather active galactic nuclei. Nowadays, the word “quasar” is often used to mean any quasi-stellar object (QSO), whether or not it emits radio waves.
- 10. When and how were quasars first found? In the 1950s and 1960s, astronomers in Cambridge, England, began to use the most sensitive radio telescopes of the day to map the entire sky The third Cambridge (3C) catalog contains hundreds of radio sources, and astronomers took visible-light photographs of these sources to see what they would look like to our eyes. The 273rd object in the 3C catalog looked like a star. But when astronomers subsequently studied more carefully the light it emits, it was discovered that 3C 273 was actually an active galaxy far away from the Milky Way. In fact, 3C 273 was the first quasar ever discovered and identified as a distant “active galactic nucleus” (AGN).

- 12. What are blazars and BL Lacertae objects? BL Lacertae was a radio source that, originally, was identified as a special kind of variable star. Today, objects like BL Lacertae are called blazars. Their spectral characteristics are very different from quasars like 3C 273, and they emit a much higher fraction of their energy at gamma ray and X-ray wavelengths than most other QSOs.
- 13. How were quasars first identified as distant, super-bright objects? In 1962 the Dutch-American astronomer Maarten Schmidt (1929–), examining the spectrum of 3C 273, realized that its pattern of emission lines was very much like that of some Seyfert galaxies, but more extreme. Using the redshift, Schmidt showed that 3C 273 was nearly two billion light-years away from Earth.
- 14. How bright can quasars (and QSOs in general) get? The brightest quasars (and, in general, QSOs) are many thousands of times brighter than all the stars in our Milky Way galaxy put together.
- 15. What does a quasar really look like? Imagine a supermassive black hole that is millions or billions of miles across and is at the center of a rapidly spinning disk of superhot gas. Around the disk and the black hole is a thick, doughnut-shaped torus of thicker, cooler gas. Matter falling toward the black hole accumulates in the torus and slowly swirls into the gas disk on its way to the black hole. Finally, right near the black hole, two super-energetic jets of matter shoot outward, above and below the disk, with matter traveling at nearly the speed of light. These jets extend thousands, even millions of light-years out into space. That is the basic picture of a quasar, or quasi-stellar object (QSO).
