Black holes are formed when giant stars collapse, leaving an intense gravitational field so strong that not even light can escape. The event horizon marks the point of no return for light and anything else, beyond which lies the singularity - an infinitely dense shrunken star. Galaxies come in different shapes - elliptical, spiral, and irregular - and can contain anything from individual stars to large groups of galaxies. Quasars are very bright and energetic objects located at the cores of distant galaxies that emit powerful radio waves and light.

Black holes (science)
Black holes are formed when giant stars collapse, leaving an intense gravitational field so strong that not even light can escape. They have an outer photon sphere where light bends but can still escape, an inner event horizon beyond which no light escapes, and a tiny, infinitely dense singularity at the center where the collapsed star is shrunken. Galaxies are large assemblies of stars and nebulae that can be elliptical, spiral, or irregular in shape, and the Milky Way is our flat, spiral galaxy within a group of galaxies.
Active Galactic Nuclei
Active Galactic Nuclei (AGN) are galaxies with incredibly bright cores that release more energy than most galaxies. It is believed that at the center of AGN is a supermassive black hole that feeds off surrounding stars and gases, and in the process releases huge amounts of energy in the form of x-rays and gamma rays. Studying AGN gives insight into black holes and ancient galaxies in the early universe.

Active galactic nuclei are galaxies that release massive amounts of energy and are extremely luminous, emitting radio waves and visible light. They typically have a supermassive black hole at the center, surrounded by an accretion disk and torus. Some have two relativistic jets. AGN include quasars, blazars, radio galaxies, and Seyfert galaxies. Astronomers study AGN to understand galactic evolution and evolution of the universe, as they are extremely luminous and can provide insights into early universe.
Agn presentation
Active galactic nuclei (AGN) are galaxies with extremely luminous central regions powered by accretion disks around supermassive black holes. The accretion disk is a ring of gas and dust circling the black hole, gradually falling onto it. Astronomers study accretion disks in AGN by observing the radiation emitted across the electromagnetic spectrum as material in the disk heats up before falling into the black hole. A "shrouded" or obscured AGN is one whose accretion disk and black hole are hidden behind thick clouds of dust, but can be detected using infrared observations able to penetrate the dust.

10.2 galaxies
Galaxies are collections of gas, dust, and stars held together by gravity. There are over 125 billion galaxies in the universe. The Milky Way galaxy contains our solar system and approximately 100 billion other stars. Galaxies come in three main shapes - spiral, elliptical, and irregular. Spiral galaxies have arms spiraling out from a central bulge, while elliptical galaxies are spherical or elliptical in shape.
Groups of stars 26.4
Star systems consist of two or more stars held together by gravity, with over half of all stars existing in systems. Star clusters form when stars are born together in the same nebula, allowing their ages to be determined. The three types of star clusters are open clusters, associations, and globular clusters. Galaxies are classified into four main categories: spiral, barred-spiral, elliptical, and irregular galaxies, which can be distinguished by their shapes, presence of spiral arms, and stages of star formation.
Different types of galaxies
There are four main types of galaxies: spiral, elliptical, lenticular, and irregular. Spiral galaxies have a central bulge and rotating spiral arms containing young stars. Elliptical galaxies are spherical and contain mostly older, redder stars. Lenticular galaxies resemble ellipticals but have a disk of gas and dust. Irregular galaxies do not fit into the other categories and often have regions of intense star formation. The Milky Way is classified as a barred spiral galaxy while Andromeda is a spiral galaxy as well.

Stars and Galaxies
Stars are giant balls of gas that produce light and heat through nuclear fusion reactions in their cores. Astronomers can determine properties of stars like temperature, luminosity, and composition by analyzing their spectra. Stars evolve over their lifetimes, with more massive stars having shorter lives and ending as supernovae. Galaxies contain billions of stars and come in spiral, elliptical, and irregular shapes. The universe originated in a massive expansion known as the Big Bang around 13.8 billion years ago.
Galaxies
There are three main types of galaxies:
- Spiral galaxies have spiral arms winding outward from a center and contain many stars and dust. The Milky Way is an example.
- Elliptical galaxies are shaped like ellipses and can be football-shaped or round.
- Irregular galaxies do not fit into the other classifications and are generally smaller than the other two types.
Nebulae & Galaxies
Nebulae are clouds of dust and gas in space. They can form new stars through gravitational clumping. There are different types of nebulae including emission nebulae like planetary nebulae that form during a star's death, and dark nebulae that block out light. Galaxies come in spiral and barred spiral shapes, containing billions of stars. The Milky Way galaxy is a barred spiral galaxy that Earth resides in.
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.

4.3 Galaxies are Different Shapes and Sizes
Low-mass stars have shorter main sequence lifetimes than high-mass stars. They use their nuclear fuel quickly and end their lives by exploding as supernovae, leaving behind neutron stars or black holes. High-mass stars spend more time in the main sequence, using their fuel more slowly. They expand into giant stars and shed their outer layers, ending their lives as white dwarfs.

Milky way galaxy
The Milky Way Galaxy is a spiral galaxy that contains our solar system. It has a disk shape with a bulge at the center, made up of stars, gas, and dust. There are three major types of galaxies - spiral galaxies which have a disk and bulge, elliptical galaxies which are round without a disk, and irregular galaxies with an irregular shape. The Milky Way Galaxy is a spiral galaxy that rotates and is held together by gravity.
Galaxy and its kinds
Galaxies are massive gravitationally bound systems consisting of stars, gas, dust, and dark matter. They come in different shapes such as elliptical, spiral, and irregular. The word "galaxy" derives from the Greek word for the Milky Way galaxy, which was thought to have been formed from milk that sprayed from Hera's breast while she was nursing the infant Heracles. Major components of galaxies include stars, star clusters, interstellar gas and dust, supermassive black holes at their centers, and dark matter.
Types of galaxies
There are an estimated 170 billion galaxies in the universe. Galaxies consist of stars, gas, dust, and dark matter that are gravitationally bound together. There are three main types of galaxies: spiral galaxies which have a bulge, disk, and halo structure; elliptical galaxies which are elongated spheres; and irregular galaxies which have no defined shape. Galaxies are further classified based on their structure.

Meteor Showers
Meteor science was not widely accepted until the Leonid meteor shower of 1833, when Americans observed over 1,000 meteors per hour. Meteoroids entering Earth's atmosphere become meteors and are visible 50-60 miles above ground, glowing brightly from friction heating the air to 3,000°F as they streak across the sky at 11-70 miles per second. Meteor showers occur annually when Earth passes through trails of meteoroids orbiting the sun in meteor streams, with notable showers including the Quadrantids in January and Perseids in August.

A galaxy is a large group of stars, gas, and dust held together by gravity. The three main types of galaxies are elliptical, spiral, and irregular galaxies. A spiral galaxy has a central bulge and outer disk with spiral arms. The Milky Way galaxy is a large barred spiral galaxy that contains our solar system. A star is a luminous ball of gas that produces energy through nuclear fusion at its core. There are several stages in a star's life including protostars, main sequence stars, red giants, and white dwarfs.
Nebula & Galaxies
Nebulae are clouds of dust and gas in space. They can form new stars when the clouds collapse under gravity. There are different types of nebulae including emission nebulae like planetary nebulae that glow from nearby starlight, and dark nebulae that block out light. When large stars explode as supernovae, they form supernova remnants like the Crab Nebula. Galaxies contain billions of stars and come in spiral, barred spiral, and elliptical shapes like our Milky Way galaxy.

Galaxies
There are billions of galaxies in the universe that come in many shapes and sizes. Galaxies are grouped into three main categories: spiral, elliptical, and irregular. Spiral galaxies are flat disks with spiral arms, elliptical galaxies are round or oval masses of stars with little gas or dust, and irregular galaxies have stars, gas, and dust spread out randomly. The Hubble Space Telescope was launched in 1990 and has helped scientists further classify galaxies and study them in more detail.
Chapter 10 Formation Of The Solar System1
1) A galaxy is a large group of stars, dust, and gas that are classified based on their shape into spiral, elliptical, or irregular galaxies.
2) Spiral galaxies have a central bulge and spiral arms where new stars are forming, and usually contain nebulae and open star clusters.
3) Elliptical galaxies are mostly made up of older stars in a blob-like shape, while irregular galaxies have been distorted by interactions with other galaxies.
Galaxies PPT.pptx
The document summarizes the different types of galaxies. There are three main types: spiral galaxies which have a central bulge and spiral arms containing stars and gas; elliptical galaxies which are spherical or cigar-shaped blobs containing only old stars; and irregular galaxies which do not fit into a defined shape category. Astronomer Edwin Hubble first classified galaxies in the 1920s into these categories which are still used today. The Milky Way galaxy, where our solar system is located, is a barred spiral galaxy with a disk of about 100 billion stars.
Milky_Way.ppt
The Milky Way Galaxy is a spiral galaxy that contains stars, dust, and gas. It has a disk shape with a central bulge and spherical halo. The galaxy contains spiral arms, globular clusters, and over 100 billion stars. While stars and gas account for only about 10% of the Milky Way's mass, the remaining 90% is made up of mysterious dark matter, which is only detectable through its gravitational effects. Understanding the nature of dark matter remains an important unsolved problem in astrophysics.
the anatomy of galaxies
There are three main types of galaxies: spiral, elliptical, and irregular. Spiral galaxies contain spiral arms where new stars are forming from dust and gas. They also have a central bulge containing older stars. Elliptical galaxies have no spiral arms, just a spherical distribution of older stars. Irregular galaxies have an irregular shape believed to be caused by interactions with other galaxies. They can have high star formation rates. Dwarf galaxies are a potential fourth category and are the most common type of galaxy overall.
Proficiency 1
There are different types of galaxies including elliptical galaxies, spiral galaxies, and irregular galaxies. Elliptical galaxies do not have ongoing star formation while spiral galaxies do. Irregular galaxies do not fit into a defined shape category. The formation of galaxies is influenced by density - denser regions collapse first under gravity to form protogalaxies that then separate into cores and halos, with flatter structures forming when densities were highest.

Galaxies and stars
There are three main types of galaxies: irregular galaxies with no defined shape, elliptical galaxies that are flattened balls containing only old stars, and spiral galaxies with a central bulge and rotating disk containing gas, dust, and younger stars. Stars form within giant clouds of gas and dust called nebulae, and their lifetime depends on their mass - smaller stars live much longer than larger ones. The universe contains these galaxies, nebulae, and stars, all bound together by gravity.
Classifying and measuring galaxies
Edwin Hubble established a classification scheme for galaxies that divides them into elliptical, lenticular, spiral, and irregular categories based on their visual appearance. Elliptical galaxies have an ellipsoidal shape and featureless profiles, while lenticular galaxies are disc galaxies that have used up their interstellar matter. Spiral galaxies consist of a central bulge and rotating disc with spiral arms where star formation occurs. Irregular galaxies have uncommon, chaotic shapes without defined structures. The document then describes measuring the sizes and distances between interacting galaxies using images from the LCOGT network.
1.1b classification of galaxies
1. The document discusses three main types of galaxies: irregular galaxies, spiral galaxies, and elliptical galaxies.
2. Irregular galaxies have no regular structure and contain regions of gas and young stars.
3. Spiral galaxies have a central bulge, disk with spiral arms, and halo, while elliptical galaxies are shaped like elongated spheres with smooth light and no axis of rotation.
Science Form 2 Chapter 11:Stars and galaxies in the universe
The universe contains galaxies, stars, and other celestial objects. Galaxies are large groups of stars, gas and dust that come in three shapes: spiral, elliptical, and irregular. Our solar system is located in the Milky Way galaxy, a medium-large spiral galaxy containing approximately 200 billion stars. Stars are formed from clouds of gas and dust called nebulae and have a life cycle from birth to death. They are classified based on characteristics like color, size, temperature, and distance, which determine their brightness.
7.3 star groups
The document discusses different astronomical objects including stars, constellations, galaxies, and the Milky Way galaxy. It notes that while stars appear single, most are actually part of binary or triple star systems. Constellations are patterns of stars that appear close together but are actually extremely far apart. Galaxies are large groups of stars, dust and gas bound by gravity, with the Milky Way being the galaxy where Earth is located.

The Galaxies Physics proyect.pptx
A galaxy is a large collection of stars, gas, and dust held together by gravity. The Milky Way galaxy is the one that contains our solar system. There are different types of galaxies including spiral, elliptical, and irregular galaxies. Estimates suggest there are between 100 billion and 200 billion galaxies in the observable universe. The smallest known galaxy is the dwarf galaxy Sextans, while the largest galaxy discovered is over 16 million light years long.
Form 3 PMR Science Chapter 9 Stars and Galaxies
Stars are giant balls of hot gases that produce heat and light through nuclear fusion reactions in their cores. Stars are classified according to attributes like temperature, brightness, chemical composition, size, and density. When stars die, they may leave behind white dwarfs, neutron stars, or black holes. Galaxies contain millions of stars and come in different shapes like spiral and elliptical.
Solar system pp
The document provides information about the solar system and beyond. It summarizes that the solar system consists of the Sun and objects that orbit it, including 8 planets. It is located within the Milky Way galaxy, which contains many stars, dust and gas. The document then provides details about the properties of objects in the solar system like planets, moons, asteroids and comets.

The binding of cosmological structures by massless topological defects
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.

Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.

Deep Software Variability and Frictionless Reproducibility
Deep Software Variability and Frictionless ReproducibilityUniversity of Rennes, INSA Rennes, Inria/IRISA, CNRS
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.
