Astronomy is love! In this presentation, I share three fascinating stories of constellations, explaining how the constellations in the sky got their name, and how each constellation is related to one another.
The document discusses several topics related to astronomy:
1) Constellations are specific areas of the sky as defined by the IAU, originally based on traditional Western asterisms. There are currently 88 officially recognized constellations.
2) An asterism is a pattern of stars within or crossing constellations, and the brightest stars in a constellation's main asterism are assigned Greek letters.
3) Some cultures have identified dark cloud constellations based on patterns they see in the Milky Way, such as the Australian Aboriginal "emu in the sky" formed by the Coalsack nebula.
Constellations are groups of stars that form pictures and tell stories. There are 88 officially recognized constellations that can be seen from different locations on Earth throughout the year. Many constellations represent mythological figures from stories created thousands of years ago by ancient cultures to explain the night sky.
A constellation is a group of stars that form an image in the sky. There are 88 officially recognized constellations in the world that were named by ancient Greeks and Babylonians over 6,000 years ago based on stories and figures. The document discusses facts about constellations like their movement and stories, the history of how they were established over centuries, and provides case studies of specific constellations like Draco the dragon, Grus the flamingo, Leo the lion, Ursa Major the big dipper, Indus, and Hydra the sea serpent.
This document discusses constellations visible in the night sky. It lists 88 known constellations and provides examples of some constellations visible in different seasons, including Orion in winter and Sagittarius in summer. While some stars appear close together, like those in the Big Dipper, they are actually light years apart in reality. The document also notes that the signs of the zodiac are based on 12 constellations and how Johannes Bayer assigned letters to the brightest stars in each constellation.
The document discusses two constellations: Gemini and Cancer. Gemini represents the Greek twins Castor and Pollux and is one of the zodiac constellations visible in the northern spring sky. Cancer represents a crab and is related to the mythology of Hercules' battle with the Hydra, where a crab distracted Hercules and was immortalized in the sky. The document provides details on the origins and mythology of both constellations, as well as facts about their visibility, location in the sky, and relation to the zodiac.
Constellations are groupings of stars that appear to form patterns in the night sky. Ancient cultures like the Babylonians and Greeks studied constellations and used them to mark seasons and in their myths and religions. Today, 88 constellations are recognized by astronomers, including Ursa Major, Orion, and Scorpius. Certain constellations like Ursa Major can be seen all year from any location in the northern hemisphere and are called circumpolar, while others like Orion are only visible during certain seasons.
This document discusses constellations and their mythology. It provides an overview of constellations classified by season, including some of the prominent constellations like Orion, Hercules, and Scorpio. The document also discusses the myths behind how these constellations came to be in the night sky, as well as how ancient cultures developed astrology based on the patterns and meanings attributed to different constellations and stars.

This document provides information about 15 different constellations through multiple choice questions and answers. It includes details about the mythology and visual representations of constellations such as Hydra, Aquila, Crux, Gemini, Pisces, Sagittarius, and others. Images are provided to illustrate each constellation's star patterns.
Ptolemy originally defined 48 constellations that were used by later astronomers and navigators. These constellations represented gods and figures from mythology and were used as a celestial calendar. In the early 20th century, the IAU standardized 88 constellations still used today to provide consistency for astronomers globally. Though constellations have evolved over millennia of human observation, their patterns continue to help people explore and understand the night sky.
1) Constellations are groups of stars that appear to form patterns in the night sky, though the stars within a constellation are often very far apart in reality.
2) Many early cultures saw patterns among the stars and associated them with myths and stories from their traditions, with most modern constellations derived from Greek mythology.
3) While constellations shift positions in the sky throughout the night and seasons due to Earth's rotation, they have been used for navigation, to map the sky, and bring order to observations of space.
Constellations are imaginary patterns formed by connecting stars in the sky, with different cultures seeing different shapes. There are 88 officially recognized constellations. The document describes several constellations visible in the northern sky during different seasons, including Ursa Major, Orion, Taurus, Gemini, Leo, Hercules, Sagittarius, and Scorpius. It also briefly mentions some constellations visible in the southern sky, such as Crux.
The document discusses several constellations visible from Earth, including the Southern Cross, a cross-shaped constellation visible in the southern hemisphere; the Big Dipper, a group of seven bright stars that point to the North Star; and Scorpius, a large constellation shaped like a scorpion that can be seen in the southern sky between June and August. The constellations help indicate directions, planting seasons, and harvesting times.
This document provides a guide to 52 constellations visible from mid-northern latitudes. It includes an introduction describing the guide's organization and features. Each constellation card contains an illustration of the stars, mythology or history behind the constellation's name, notable astronomical objects within it, and a mnemonic to remember it. The constellations are grouped by their visibility during each of the four seasons.
The document discusses several constellations including Hercules, Gemini, and Canis Major. It provides details on the mythology and history behind their names, notable stars within each constellation, and their locations in the night sky. Key information includes that Hercules represents the Greek hero and contains the star Alpha Her, Gemini means "twins" and contains Castor and Pollux, and Canis Major means "great dog" and is home to Sirius, the brightest star.
Throughout human history and across many different vultures, names, and mythical stories have been attributed to the stars and patterns in the night sky, this gives birth to constellations. Constellations is a group of stars forming a pattern that is traditionally named after its apparent form or identified with a mythological figure.
The document provides an introduction to Ininewuk (Cree) perspectives on astronomy and constellations. It discusses several Ininewuk stories associated with constellations visible in the northern skies, including Ochekatchakosuk (Big Dipper), which explains how summer came to be, Atima Atchakosuk (Little Dipper), about how dogs came to humans, and Mista Muskwa (Big Bear), about how bullies are dealt with. It aims to share these ancestral worldviews with First Nations students.
Ursa Major, also known as the Great Bear, is a well-known constellation visible in the northern hemisphere. It contains seven bright stars that form an asterism known as the Big Dipper. The Big Dipper has also been called the Plough and is an important marker for finding north. Ursa Major has cultural significance in many societies and its stars have taken on names from Arabic, Greek, Latin and other languages over centuries of observation.
The document discusses several constellations visible in the Northern sky, including the Big Dipper, Cassiopeia, Cepheus, Draco, and Ursa Minor. The Big Dipper is part of the constellation Ursa Major and resembles a ladle. Cassiopeia forms a W or M shape and is easily seen. Cepheus is house-shaped and never dips below the northern horizon. Draco is named after a dragon and its brightest star is in its tail. Ursa Minor is also known as the Little Dipper or Little Bear and contains the North Star. Constellations are groups of stars that appear to form patterns from Earth but are not necessarily close together in space.
Constellations were imagined as pictures formed by groups of stars and were used to tell myths and stories by ancient cultures. Astronomers have now identified 88 official constellations, some of which can only be seen at certain times of year as the Earth orbits the sun. The document then provides fun facts about several specific constellations, including Ursa Major, Ursa Minor, Pegasus, Pisces, and Leo. It concludes with true/false questions about constellations.
The document summarizes information about constellations and astronomical instruments. It discusses how constellations are patterns of stars that form shapes in the sky. The International Astronomical Union officially recognizes 88 constellations. It also describes some famous constellations like Orion, Ursa Major, Cassiopeia, and Hercules from Greek mythology. Finally, it discusses several types of advanced telescopes used by astronomers, including the Hubble Space Telescope, ultraviolet telescopes, x-ray telescopes, and the Chandra X-ray Observatory.
The document discusses various topics relating to stars and constellations. It begins by explaining that stars vary in size, color, and brightness. There are approximately 400 billion stars in the Milky Way galaxy and 170 billion other galaxies. The document then discusses the characteristics of stars such as their temperature, color, brightness, sizes, distances, and chemical compositions. It also explains how early humans used constellations for navigation, timekeeping, and agriculture. Finally, it provides examples of constellations visible from the Philippines at different times of the year.
This document discusses constellations from both a mythological and scientific perspective. It begins by defining constellations as groups of stars that appear to form patterns from Earth's point of view, though the stars are not physically close. Many constellations derive from figures in Greek mythology. The document then discusses how the night sky appears different depending on one's location and viewpoint. It concludes by noting that while constellations were meaningful for ancient cultures, modern astrophysics has revealed stars to be just a small part of a much larger universe.
The document provides an introduction to constellations visible in the night sky, including how to find them and their histories. It begins by explaining how people have observed patterns in the stars for millennia and then describes how to start identifying constellations such as the Big Dipper and Polaris. The rest of the document discusses specific constellations like Orion's Belt, Ursa Major, and zodiac signs including Taurus and Pisces. Brief summaries are given about the mythology and stories associated with each constellation.
The document discusses constellations, which are patterns of stars recognized by various ancient cultures and formally defined by the IAU. Constellations were used for navigation, tracking seasons, and preserving myths. The IAU recognizes 88 constellations that fall within designated boundaries and include a variety of figures from mythology and science. Smaller unofficial patterns within constellations are called asterisms. Six constellations in the northern sky are always visible from a latitude of 28 degrees north.
This document provides information about three constellations: Ursa Major, Orion, and Cassiopeia. Ursa Major is a prominent summer constellation containing seven stars that form the shape of a ladle or question mark. Orion is a recognizable winter constellation known as "The Hunter" with three stars forming its belt. Cassiopeia is another winter constellation with a distinctive W or M shape named after the mythological queen.
Beliefs and practices about constellations and astrology.docxVuongmobile28
This document discusses the history and uses of constellations and astrology. It describes how ancient cultures like the Greeks, Romans, Chinese, Japanese, Babylonians, and Sumerians studied constellations and used them for religious purposes and astrology. They believed the positions of stars and planets influenced people's lives. Today, constellations are used to track satellites, indicate directions, and locate specific stars and galaxies. The International Astronomical Union delineated boundaries for the 88 official constellations.
The document provides information about constellations from different perspectives. It discusses how ancient cultures imagined patterns in the stars and gave them names representing animals, objects, and people. It also explains how constellations like Orion were seen differently by various early civilizations. Additionally, it describes how constellations like Gemini were used by the Matigsalug Manobo people of the Philippines to indicate agricultural seasons and activities. Finally, it discusses the current uses of constellations by astronomers for naming and locating stars, and their differing roles in astronomy versus astrology.
This document provides descriptions of each of the 12 tracks on the album "Music Inspired by Zodiac". Each track is inspired by and named after a different zodiac sign. The album combines many styles of music from rock and folk to trip-hop to ethnic music. It was carefully produced in the studio to keep the listener engaged through gradual, slow charms and moving them into another world. The compositions feature guitars, keyboards, drums, percussion, vocals, didgeridoo, flutes, and fifes performed by the two main musicians and occasional guest musicians.
Constellations have been observed and documented since 1000 BC by early civilizations like the Babylonians, with the ancient Greeks recording many myths associated with patterns of stars. Constellations refer to recognizable patterns of stars often relating to Greek mythology, while asterisms are subsets within constellations that form other shapes, such as the stars that compose the Big Dipper within the larger Ursa Major constellation. Some constellations exist merely as shapes people imagine they see within clouds or patterns of stars, like the fictional "Eddie the Head" believed to bring misfortune and death to those who glimpse it.

The document discusses constellations, zodiacs, and zodiac signs. It provides descriptions of each zodiac sign's personality traits, both positive and negative. It also lists some famous people and their zodiac signs.
This document provides standards and materials for a 4th grade lesson on constellations. The lesson teaches students about how the rotation of the Earth affects the stars we see at night and their positions in the sky throughout the year. Students will learn what constellations are and how to identify different constellations. They will then create their own constellations by poking holes in black paper to form shapes and try to identify each other's constellations using flashlights. The lesson will be assessed through a worksheet identifying various constellations.
This document discusses the key components and functions of computers. It describes the three types of computers based on size and storage capacity, as well as the four main parts of a computer: input, output, memory, and the central processing unit (CPU). The CPU is made up of the control unit and arithmetic logic unit. Memory is divided into random access memory (RAM) and read only memory (ROM). The document also defines common computer terms like bits, bytes, and memory sizes and provides an overview of how computer chips are made.
This document is an e-lesson about the surprises one might find in a meadow. It provides background on the poet Louis Phillips who wrote the poem "Meadow Surprises" that is included. The poem describes some of the sights one might encounter if they take a walk through a meadow, listening and looking closely. It mentions seeing butterflies, rabbits, dandelions that have gone to seed, and discovering animal homes like burrows and ant mounds hidden in the grass. The lesson encourages readers to explore meadows themselves to discover their hidden surprises.

Key areas covered include the history of astrology, traits associated with different zodiac signs, personality types and their suitability to certain signs, and characteristics of bosses based on their astrological signs.
This document provides an introduction to constellations and the horoscope/zodiac. It explains that constellations are imaginary patterns formed by groups of stars and were used by ancient people to tell stories. The document then describes each of the 12 zodiac signs, including the corresponding constellation in astronomy and its symbol, ruling planet, and dates in astrology along with brief mythical origins. Key terminology around astronomy, astrology, and star charts is also defined.
The document discusses how the rotation of the Earth causes the position and length of shadows to change throughout the day. It notes that in the morning shadows are long and point west, becoming shorter until reaching their shortest at noon, then lengthening and pointing east in the afternoon as the sun sets in the west.
Teacher training presentation used during Universe in the Classroom phase 1 (2014-2015). Covers the following topics: Moon, Earth, Sun, Solar System and Constellations using the Universe-in-a-Box hands-on toolkit.
Astrology is the study of how celestial objects influence human lives and destiny. It divides people into 12 signs based on their birth date, each associated with different personality traits. The signs are also grouped into the four elements of fire, earth, air and water. While astrology can provide insights and predict events, its importance ultimately lies in the direct influence the sun, moon and stars have on our daily lives and reactions.
Zodiac signs: meanings, symbols and activitiessergioaltea

For each sign, it lists both positive and negative adjectives to describe people born under that sign. It then encourages the reader to create their own zodiac sign and composition.
This document provides an introduction to constellations and backyard astronomy. It discusses what constellations are, how to locate Polaris, and some key things needed for stargazing like darkness, star maps, binoculars, and warm clothing. It then describes several prominent northern circumpolar constellations like Ursa Minor, Ursa Major, Cassiopeia, Cepheus, and Draco. Finally, it summarizes some common zodiac constellations like Aquarius, Aries, Cancer, Gemini, Leo, Libra, Pisces, Sagittarius, Scorpius, Taurus, and Virgo.
The document discusses several theories about the origin and creation of the universe:
1) The Big Bang Theory proposes that the universe originated from an explosion of dense matter around 10-20 billion years ago.
2) Some experts argue it was not an explosion but an expansion, like a balloon growing in size.
3) String Theory hypothesizes that subatomic particles are one-dimensional strings and their interactions shaped the early universe.
4) The Creationist Theory states that God created the universe, Earth, and humanity as described in the Bible over seven days.
Astrology has a long history dating back to ancient civilizations like Babylon and Egypt. While it was considered a science in Greek times, the early Christian church condemned it as occult and Satanic. Astrology waxed and waned in popularity over the centuries. Modern astrology still relies on the earth-centered model of Ptolemy from over 1500 years ago, which has been disproven by astronomy. The document concludes that astrology is not scientific but rather a superstition and tool of Satan according to scripture.
Information for Primary School students on stars and constellations. This PowerPoint uses some slides from http://www.slideshare.net/winga1sm/star-powerpoint-3308182 and the rest has been created by me.
Constellations are groups of stars that appear to form patterns in the sky, though the stars are not physically close together. There are 88 officially recognized constellations. Polaris, also known as the North Star, has been used for navigation for thousands of years as it appears nearly stationary in the sky and always points north. Polaris is actually a triple star system composed of three stars in orbit around each other. Virgo is the second largest constellation and is associated with harvest. Orion is one of the most prominent winter constellations, depicted as a hunter, with his dog Sirius at his feet. According to Greek mythology, Orion boasted that nothing could kill him but was later killed by a scorpion
The document contains summaries of various constellations including when they are visible, key facts about their stars and mythology. Some of the constellations mentioned include Cancer, which is small and a zodiac sign seen in March. Sagittarius is best seen in August, part of the zodiac and visible between latitudes of 55-90 degrees. Virgo is the second largest constellation, seen best in May, with the symbol of and meaning 'virgin' in Latin.
Stars undergo nuclear fusion reactions in their cores to produce energy, while planets do not generate their own power. The brightness and luminosity of stars are described using apparent magnitude and absolute magnitude scales. Parallax is used to measure the distance to nearby stars by observing their position shift from different points in Earth's orbit. Constellations are patterns of stars in the sky that represent figures from mythology and have defined boundaries.
A constellation is a group of stars that appears to form a pattern or picture like Orion the Great Hunter, Leo the Lion, or Taurus the Bull. Constellations are easily recognizable patterns that help people orient themselves using the night sky. There are 88 “official” constellations.
The document discusses constellations and how they are groupings of stars that form patterns in the night sky. It describes how constellations got their names from ancient civilizations and how the modern constellations were standardized by the IAU. It provides examples of famous constellations like Orion, Ursa Major, and the zodiac constellations. The document also explains that while stars appear close together in constellations, they can actually be very far apart in real space.
This document provides information on several constellations visible in the Northern Hemisphere through a series of slides. It describes the shapes and stories behind constellations like Ursa Major, Ursa Minor, Cepheus, Cassiopeia, Draco, Orion, and others. It also discusses circumpolar constellations that can be seen all year and the relationship between the zodiac constellations and the ecliptic path of the sun.
This document contains 25 questions for an astronomy quiz. It provides the rules that it is a written round with 25 questions, and star marked questions will be used to resolve ties. It then lists the questions and possible answer choices. The questions cover topics in astronomy such as constellations, planets, stars, astronomical phenomena, and discoveries in the field of astronomy.
The phenomena being described is a solar eclipse. Some key details that indicate this:
- It occurred on a specific date (May 29th, 1919)
- Two teams were sent to two separate sites for observation, implying it was a widespread event visible from multiple locations.
- It was one of the most awaited ones, suggesting it was a significant astronomical event.
- The eclipse was the only chance to "turn off" the light from the Sun, allowing certain observations.
So in summary, the total solar eclipse of May 29th, 1919 was being observed to test Einstein's theory of general relativity by measuring the deflection of starlight by the Sun's gravitational field during the eclipse.
Ptolemy listed 48 constellations in his Almagest, including 21 northern, 12 zodiac, and 15 southern constellations. The earliest evidence of constellations comes from Mesopotamian star catalogs from 1300-1000 BC which included the farming calendar tradition and divine associations of constellations. Orion correlation theory suggests that ancient Egyptians believed gods descended from the belt of Orion and Sirius and instigated the human race, which may explain why the Great Pyramid air shafts point to Orion.

Ursa Major is a constellation visible in the northern hemisphere and is also known as the Great Bear. The seven brightest stars form an asterism known as the Big Dipper in North America and the Plough in the UK. These stars include Dubhe and Alkaid and are useful for finding Polaris, the North Star. Several bright galaxies can also be found in Ursa Major. In mythology, Ursa Major has been associated with a bear from Greek mythology where Zeus transformed a woman into a bear and placed them in the sky.
The document provides an introduction to constellations visible in the night sky, including how to find and identify some of the major constellations. It discusses how people have observed patterns in the stars for millennia and describes techniques for stargazing without equipment, such as using the Big Dipper to locate Polaris. The document then profiles several constellations like Ursa Major, Ursa Minor, Orion, and zodiac constellations including Pisces, Aries, and Taurus, providing myths and stories associated with each.

science 9 quarter 3: Constellations and Astronavigation PPT.pptxteleganne21
This document discusses early astronomical navigation tools and constellations. It describes the compass, astrolabe, sextant and telescope as tools used historically for navigation by measuring celestial bodies. It also summarizes the mythology and identifying features of the constellations Orion, Ursa Major, and Ursa Minor.
The document summarizes information about stars and planets in the solar system. It describes the eight planets - Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune - including their orbits, diameters, masses and origins of their names from mythology. It also provides facts about stars, such as there being 200 billion stars in the Milky Way and sizes ranging from the largest star VY Canis Majoris to the smallest VB 10. Stars are formed from the gravitational collapse of gas and dust in nebulas and fuse hydrogen in their cores through nuclear fusion.
The document discusses the possibility that the traditional zodiac signs used in astrology may no longer be accurate due to precession of the equinoxes. It notes that the constellations the sun was aligned with at the time of one's birth no longer match up with the months assigned to the 12 zodiac signs due to a shift over thousands of years. Some key points made include that a 13th zodiac sign called Ophiuchus is proposed to be added, which would result in some people previously thought to be one sign now being considered a different one. The document also discusses the history and origins of the traditional 12 zodiac signs and constellations, as well as concepts such as tropical
The Little Dipper is a constellation that is visible in the northern sky year-round. It is also known as Ursa Minor, which is Latin for "Little Bear." The stars in the Little Dipper are supposed to form the shape of a ladle's handle and a small bear. Throughout history, the group of stars have also been associated with myths involving a dragon's wing and relationships to other constellations like Ursa Major.
Astronomical event before the advent of telescopeoryzasativa0720
- Ancient Babylonian and Egyptian civilizations systematically observed and recorded the motions of the sun, moon, and planets without telescopes. They noted the sun rises in the east and sets in the west, and its rising and setting points varied over the course of a year.
- They observed the moon's changing appearance over 29.5 days in its phases from a thin crescent to a full circular disk. Lunar eclipses where the Earth casts its shadow on the moon were also noticed.
- Constellations were patterns of visible stars that helped with navigation, timekeeping of calendars, and recognizing stars. Five planets - Mercury, Venus, Mars, Jupiter, and Saturn - could be seen without telescopes
Uranus was discovered by William Herschel in 1781. It is the 7th planet from the Sun and is similar in composition to Neptune as an "ice giant" with a atmosphere containing water, ammonia and methane. Uranus has a unique configuration with its axis nearly sideways resulting in its poles lying where other planets have their equators.
Authoring a personal GPT for your research and practice: How we created the Q...Leonel Morgado
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.
Describing and Interpreting an Immersive Learning Case with the Immersion Cub...Leonel Morgado
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.

The binding of cosmological structures by massless topological defectsSérgio Sacani
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
JAMES WEBB STUDY THE MASSIVE BLACK HOLE SEEDSSérgio Sacani
The pathway(s) to seeding the massive black holes (MBHs) that exist at the heart of galaxies in the present and distant Universe remains an unsolved problem. Here we categorise, describe and quantitatively discuss the formation pathways of both light and heavy seeds. We emphasise that the most recent computational models suggest that rather than a bimodal-like mass spectrum between light and heavy seeds with light at one end and heavy at the other that instead a continuum exists. Light seeds being more ubiquitous and the heavier seeds becoming less and less abundant due the rarer environmental conditions required for their formation. We therefore examine the different mechanisms that give rise to different seed mass spectrums. We show how and why the mechanisms that produce the heaviest seeds are also among the rarest events in the Universe and are hence extremely unlikely to be the seeds for the vast majority of the MBH population. We quantify, within the limits of the current large uncertainties in the seeding processes, the expected number densities of the seed mass spectrum. We argue that light seeds must be at least 103 to 105 times more numerous than heavy seeds to explain the MBH population as a whole. Based on our current understanding of the seed population this makes heavy seeds (Mseed > 103 M⊙) a significantly more likely pathway given that heavy seeds have an abundance pattern than is close to and likely in excess of 10−4 compared to light seeds. Finally, we examine the current state-of-the-art in numerical calculations and recent observations and plot a path forward for near-future advances in both domains.
Evidence of Jet Activity from the Secondary Black Hole in the OJ 287 Binary S...Sérgio Sacani
Wereport the study of a huge optical intraday flare on 2021 November 12 at 2 a.m. UT in the blazar OJ287. In the binary black hole model, it is associated with an impact of the secondary black hole on the accretion disk of the primary. Our multifrequency observing campaign was set up to search for such a signature of the impact based on a prediction made 8 yr earlier. The first I-band results of the flare have already been reported by Kishore et al. (2024). Here we combine these data with our monitoring in the R-band. There is a big change in the R–I spectral index by 1.0 ±0.1 between the normal background and the flare, suggesting a new component of radiation. The polarization variation during the rise of the flare suggests the same. The limits on the source size place it most reasonably in the jet of the secondary BH. We then ask why we have not seen this phenomenon before. We show that OJ287 was never before observed with sufficient sensitivity on the night when the flare should have happened according to the binary model. We also study the probability that this flare is just an oversized example of intraday variability using the Krakow data set of intense monitoring between 2015 and 2023. We find that the occurrence of a flare of this size and rapidity is unlikely. In machine-readable Tables 1 and 2, we give the full orbit-linked historical light curve of OJ287 as well as the dense monitoring sample of Krakow.
Candidate young stellar objects in the S-cluster: Kinematic analysis of a sub...Sérgio Sacani
Context. The observation of several L-band emission sources in the S cluster has led to a rich discussion of their nature. However, a definitive answer to the classification of the dusty objects requires an explanation for the detection of compact Doppler-shifted Brγ emission. The ionized hydrogen in combination with the observation of mid-infrared L-band continuum emission suggests that most of these sources are embedded in a dusty envelope. These embedded sources are part of the S-cluster, and their relationship to the S-stars is still under debate. To date, the question of the origin of these two populations has been vague, although all explanations favor migration processes for the individual cluster members. Aims. This work revisits the S-cluster and its dusty members orbiting the supermassive black hole SgrA* on bound Keplerian orbits from a kinematic perspective. The aim is to explore the Keplerian parameters for patterns that might imply a nonrandom distribution of the sample. Additionally, various analytical aspects are considered to address the nature of the dusty sources. Methods. Based on the photometric analysis, we estimated the individual H−K and K−L colors for the source sample and compared the results to known cluster members. The classification revealed a noticeable contrast between the S-stars and the dusty sources. To fit the flux-density distribution, we utilized the radiative transfer code HYPERION and implemented a young stellar object Class I model. We obtained the position angle from the Keplerian fit results; additionally, we analyzed the distribution of the inclinations and the longitudes of the ascending node. Results. The colors of the dusty sources suggest a stellar nature consistent with the spectral energy distribution in the near and midinfrared domains. Furthermore, the evaporation timescales of dusty and gaseous clumps in the vicinity of SgrA* are much shorter ( 2yr) than the epochs covered by the observations (≈15yr). In addition to the strong evidence for the stellar classification of the D-sources, we also find a clear disk-like pattern following the arrangements of S-stars proposed in the literature. Furthermore, we find a global intrinsic inclination for all dusty sources of 60 ± 20◦, implying a common formation process. Conclusions. The pattern of the dusty sources manifested in the distribution of the position angles, inclinations, and longitudes of the ascending node strongly suggests two different scenarios: the main-sequence stars and the dusty stellar S-cluster sources share a common formation history or migrated with a similar formation channel in the vicinity of SgrA*. Alternatively, the gravitational influence of SgrA* in combination with a massive perturber, such as a putative intermediate mass black hole in the IRS 13 cluster, forces the dusty objects and S-stars to follow a particular orbital arrangement.

3. INTRODUCTION
This power point presentation is about 12 different constellations
I chose to study over the Fall/Winter semester. All of the 12
constellations I chose because I felt they were the most
interesting or ones I could relate too. Each constellation has 3-4
pages explaining their facts, how to find them, their myths and
special objects. There are many different constellations all of
which are unique and interesting in their own. I hope readers will
find this information informative and artistic.

5. ABOUT CONSTELLATION DORADO
• Official Name: Dorado
• Spanish Name: Dorado (Coryphaena hippurus) meaning
“Dolphinfish”
• History: Dorado was one of the first constellations seen by
Dutch navigators Pieter Dirkszoon and Petrus Plancius a
Dutch astronomer. The constellation represents a colorful
surface-dwelling dolphinfish found in tropical waters.
• Myth: Pieter an Petrus observed the dolphinfish chasing the
flying fish, and that is why Dorado was placed in the sky
next to the constellation named Volans because it
represents a flying fish.
5
6. HOW TO FIND DORADO
• It can be seen at latitudes between
+20°and -90° and best seen at 9 p.m.
during the month of January.

11. A Little About Pictor
Pictor is a constellation that lies in the Southern Hemisphere. Pictor got its name from the
Equueleus Pictoris ( the painter’s easel). Pictor was named by Nicolas-Louis de Lacaille a French
astronomer and priest, in the 18th century.
Mythology: The constellation was considered ”new” back then so it doesn’t have much
mythology. What is known is that Equueleus Pictor means, ” The artist Easel and Easel is a
Germanic synonym for donkey Nicolas-Louis de LaCaille named most of his constellation
creations after artistic and technical instruments. Pictor, “the easel”, was the same
deal. Originally titled le Chevalet et la Palette, French for “the easel and palette”, the name was
Latinized to Equuleus Pictorius for his published work, Coelum Australe Stelliferum. In 1845, for
the British Association Catalogue, it was shortened to the current name, Pictor.
11
12. PICTOR FACTS • Pictor can be found between Canopus (a
star) in Carina Constellation and the
Magellanic Cloud in Constellation Dorado
and Mensa.
• Pictor has 3 stars in it, Alpha Pictoris, Beta
Pictoris and Delta Scuti.
• It is located in the first quadrant of the
Southern hemisphere between +26 and -
90 degrees.

14. ABOUT VOLANS
Common Name: Volans
Original Name:
Piscis Volans
Translation of Name:
The Flying Fish
14
15. MYTH & HISTORY
Back Story: Volans is one of 12 constellations that were brought up
by Dutch navigators Pieter Dirkszoon Keyser and Frederick de
Houtman in the late 16th century. The constellation was first seen on
Petrus Plancius globe in 1598. Plancius then called the constellation
Vilegendenvis. In 1603 a man named Johann Bayer added the
constellation to his star atlas Uranometria and it was the name Piscis
Volans “the flying fish”. It was called that until the mid-19th century.
John Herschel was the man who suggested it be shortened to Volans.
Volans is a representation of a tropical fish that can jump out of the
water and glide in the air on wings. The flying fish in the night sky
appears that it is being chase by predatory fish like Dorado ( a
constellation I previously did).

A LITTLE SOMETHING ABOUT HYDRA
19
20. HYDRA’S HISTORY
Hydra is a mythological hybrid that of a serpent,
lion and bird. Hydra is the largest of 88
constellations and occupies 1303 square degrees
in the night sky. The Myth of Hydra is that it
Hydra is an adaptation from a Babylonian
constellation MUL.APIN that includes a serpent.
The shape of the constellation is a twisting snake.
Hydra was a water snake that a crow served
Apollo in a cup when the crow was sent to get
him water. Apollo saw what the crow was trying
to do and threw the crow, snake and cup into the
sky. It is also associated with a myth that Hydra
was some kind of monster that has many heads
and was killed by Hercules represented in another
constellation. It was believed that if Hydra’s head
was cut off two more would grow, but Hercules
burned out the roots of the head and prevent them
from growing.

25. THE MYTH OF VIRGO
The Greeks and Romans
related Virgo with their
goddess of wheat/agriculture,
Demeter-Ceres who is the
mother of Persephone-
Proserpina. Sometimes, she
was known as the virgin
goddess Lustitia or Astraea,
holding the scales of justice in
her hand as the constellation
Libra.
In India constellation Virgo is
related to maidens, purity and
fertility. According to Indian
mythology Virgo was Kauni,
mother of the great god Krishna.
The Babylonians linked her with the
goddess Ishtar. When she went into
the underworld to reclaim her
husband Tammuz, god of the
Harvest, the earth went dark and
nothing grew. The great gods were
forced to get involved, she and
Tammuz were saved, and the earth
started to bloomed again.
Virgo has many different stories myths,
depending on the culture they vary...
Virgo is supposed to represent
Astraea, the daughter of the Greek
god Zeus and Titaness Themis, the
personification of the goddess of
Justice who was the last of the
deities to abandon the Earth at the
end of the fabled Golden Age.

30. LIBRAAND IT’S MYTH
• Libra was known in Babylonian astronomy as MUL Zibanu ("the
scales"), or and also as the Claws of the Scorpion. The scales were held
as very important to the sun god Shamash, who was known as the patron
of truth and justice. It was also pictured as the Scorpion's Claws in
ancient Greece. Because of that, Libra has been associated with law,
fairness and civility.
• Libra also has a mythology to the Arabian. In Arabic zunaba means
"scorpion's claws”, just like the myth above. It has also been said that the
scales are a representation of equality. Also when the sun entered this
part of the ecliptic at the autumnal equinox, the days and nights are equal
and Libra is known to be related to that. Libra's status as the location of
the equinox earned the equinox the name "First Point of Libra", because
of the exact spot of the equinoxes.

34
35. MYTHOLOGY
Ophiuchus, The Serpent Holder, goes along with Aescupalius, the
“noted healer” of Greek legend. His mother Coronis was persued by
the god Apollo and she got pregnant. However, this didn’t stop her
falling for someone else…. a mortal, named Ischys. The God had left
a white crow to keep watch on Coronis and, when it told that she had
been unfaithful, Apollo was so furious that it didn’t immediately peck
out Ischys's eyes that he cursed the bird and turned it black. When
Artemis, Apollo's huntress sister, heard how Coronis acted, she shot a
bunch of arrows into her. Apollo saved his unborn son, named him
Aesculapius, and took him to Chiron, the kind and really smart
centaur, who taught him the art of medicine. The youth mastered the
art completely, so much so that Hades, King of the Underworld,
feeling threatened should Aesculapius be able to raise the dead,
complained to Zeus. The great god regrettably decided that
Aesculapius must die, and struck him with a thunderbolt, thereafter
placing him among the stars. To this day, Aesculapius and the serpent
are associated with healing, and all physicians take the Hippocratic
oath (Hippocrates supposedly being a descendant of Aesculapius).

ABOUT?
Indus was created by the Dutch astronomer Petrus
Plancius in the late 16th century and first depicted in
a star in Johann Bayer’s Uranometria atlas in 1603.
Plancius depicted Indus as a naked man holding
arrows in both of his hands. The myth of Indus
started by 16th century creation of Pieter Dirkszoon
Keyser and Frederick de Houtman. They were two
Dutch navigators who observed the Southern skies
during their expedition to the East Indies. It was
named for the Native Americans that European
explorers met along the way.

Greek
Roman
Ancient Babylonian
Arab Egyptian
Sumerian
Zeus kidnaps a young boy named
Ganymede. Zeus desired the youth
and sent Aquila his pet Eagle to
capture the boy and bring him to
mount Olympus. He made Ganymede
a servant that brought wine cups to
Greek Deities.
The story is similar to Greek however
the names are changed. Zeus in
Roman is Jupiter and Ganymede is
Aquarius who was the king of Troy’s
son.
Aquarius was depicted as a water
bearing God. His image was even
carved on stone buildings. When
he brought the annual month of
rain, they called it the curse of rain.
Aquarius is not a being or God, instead he
is a bucket. This is because with the Arabs
that forbids any kind of depictions of any
forms of humans or beings.
Aquarius is the keeper of the Nile
River. He pours the water into the
river and creates rain so that the
Nile will overfill and nourish the
valley of farm land.
Aquarius was known as the barrier of a
destructive flood that ravished the entire
planet. This is considered the Great Flood
from Noah’s. Aquarius held the vessel of
flood waters from heaven onto the Earth.
