Galaxy - Wikipedi

  1. A galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter. The word galaxy is derived from the Greek galaxias ( γαλαξίας ), literally milky, a reference to the Milky Way
  2. A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems. A galaxy is held together by gravity. Our galaxy, the Milky Way, also has a supermassive black hole in the middle. When you look up at stars in the night sky, you're seeing other stars in the Milky Way
  3. Galaxies. A spiral galaxy in the Hubble Ultra Deep Field image. (Credit: NASA, ESA, S. Beckwith (STScI) and the HUDF Team) A galaxy is a large group of stars, gas, and dust bound together by gravity. Our solar system resides in the Milky Way galaxy, a spiral galaxy that is part of a group of galaxies called the Local Group
  4. There are about 51 galaxies in the Local Group (see list of nearest galaxies for a complete list), on the order of 100,000 in our Local Supercluster, and an estimated 100 billion in all of the observable universe. The discovery of the nature of galaxies as distinct from other nebulae ( interstellar clouds) was made in the 1920s
  5. In 1936, Hubble debuted a way to classify galaxies, grouping them into four main types: spiral galaxies, lenticular galaxies, elliptical galaxies, and irregular galaxies
  6. Astronomers classify galaxies into three major categories: elliptical, spiral and irregular. These galaxies span a wide range of sizes, from dwarf galaxies containing as few as 100 million stars to giant galaxies with more than a trillion stars

A galaxy is any of the systems of stars and interstellar matter that make up the universe. Many such assemblages are so enormous that they contain hundreds of billions of stars. Galaxy clusters are gravitationally bound groupings of galaxies, numbering from the hundreds to the tens of thousands According to NASA, galaxies are a representation of how matter in the universe was organized - at least, on the large scale. (Scientists are also interested in particle types and quantum. The Antennae Galaxies (NGC 4038/4039 or Caldwell 60/61) are two colliding galaxies located about 45 million light-years away from the Earth in the direction of the Corvus (Crow) constellation. When seen from ground-based telescopes, the galaxy pair looks like the head and antennae of an insect, because of two tidal tails that extend far from. Many of those points of light are actually galaxies — collections of millions to trillions of stars. Galaxies are composed of stars, dust and dark matter, all held together by gravity

Description. There are galaxies of different sizes and type. Typical galaxies range from dwarfs with as few as ten million (10 7) stars up to giants with a hundred trillion (10 14) stars, all orbiting the galaxy's center of mass.Galaxies may contain many multiple star systems, star clusters, and various interstellar clouds.The Sun is one of the stars in the Milky Way galaxy; the Solar System. We would like to show you a description here but the site won't allow us For hundreds of years, astronomers—scientists who study things in space—have been trying to figure out where our solar system is in the universe. They have learned that our Sun is part of a huge group of stars called a galaxy. Our galaxy is called the Milky Way. The Milky Way is just one of billions of galaxies. WHAT ARE GALAXIES MADE OF

Even our own Milky Way Galaxy is thought to have a bar, but perhaps not so prominent as the one in NGC 1365, shown above Galaxies can also be thin and flat with tentacle-like arms — just like the Milky Way. 6. Galaxies come in irregular shapes, too, including many dwarf galaxies. These galaxies, the smallest in the universe, contain only a few hundred or a few thousand stars (compared with 100 billion stars in the Milky Way). 7 In this BrainPOP movie, Tim and Moby will teach you how to be one by learning about the wonders of galaxies, those massive clusters of stars, gas, and dust. Learn just how many zillions of objects a galaxy can have (okay, a zillion isn't a real number...) in addition to what exactly is lurking inside each galaxy

What made galaxies and galaxy clusters, superclusters, voids, and filaments look the way they do? The existence of such large filaments of galaxies and voids is an interesting puzzle because we have evidence (to be discussed in The Big Bang) that the universe was extremely smooth even a few hundred thousand years after forming.

Galaxies are collections of stars, gas, dust and dark matter held together by gravity. Their appearance and composition are shaped over billions of years by interactions with groups of stars and other galaxies. Using supercomputers, scientists can look back in time and simulate how a galaxy may have formed in the early universe and grown into. Galaxies range from 10,000 to 200,000 light-years in size and between 10 9 and 10 14 solar luminosities in brightness. Galaxies have certain features in common. Gravity holds the billions of stars together, and the densest region is in the center, called a core or bulge. Some galaxies have spiral or pinwheel arms Elliptical galaxies, which essentially consist of only a nuclear bulge component are subdivided among seven ellipticity classes from E0 (circular) to E7 (cigar shaped). Numerically the ellipticity is given by. 10 (a-b)/a where a is the length of the major axis and b is the length of the minor axis. Of course, the Hubble Classification does not.

Galaxies Facts & Information A galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter. Galaxies are divided into four main groups: spiral, barred spiral, elliptical, and irregular Clusters of Galaxies. Most galaxies are not alone in the vast expanse of space, but are connected to one or more other galaxies by gravity.The same force that holds you onto the Earth can keep many individual galaxies bound together. Groups can be small, such as two galaxies orbiting each other, or large, like the rich Coma cluster of thousands of galaxies extending for more than ten million. Galaxies are not always solitary bodies. They are frequently grouped together and sometimes interact or even collide. Usually groups comprise of up to 50 galaxies and these groups are connected to superclusters of groups throughout the universe Elliptical galaxies have very little activity and contain mostly old stars of low mass, because there gasses and dust which is needed to form new stars, is quite lacking. Elliptical galaxies vary in size, from small dwarf galaxies to enormous galaxies. An example of a giant elliptical galaxy is ESO 325-G004, while Leo I is a dwarf elliptical. galaxy: [noun] milky way galaxy. any of the very large groups of stars and associated matter that are found throughout the universe

This sample of merging galaxies is assembled from SDSS Galaxy Zoo 1 data. It is a homogenous sample of galaxies (0.005 < z < 0.1) with spectroscopy for at least one of two merging galaxies in the pair. Value-added GZ data includes the morphologies of the merging galaxies as well as the relative stage of the merger Galaxies range from a few thousand to a million light-years in diameter. A galaxy is a cluster of stars, dust, and gas which is held together by gravity. Galaxies are scattered throughout the universe and they vary greatly in size. A galaxy may be alone or it may be in a large group of galaxies called a supercluster Myriads of galaxies, visible only to those with medium-to-large telescopes, shine among the stars in the Realm of the Galaxies. Study of the Coma Cluster of galaxies aided in the discovery of. The L-Galaxies galaxy formation model includes physical prescriptions for processes such as gas cooling, star formation, supernova feedback, formation and growth of black holes, AGN feedback and galaxy interactions and mergers that have been gradually developed over the years. A few simple slides describing the main components of the model can. There are billions of galaxies in the Universe. Some are very small with only a few million stars, while others could have as many as 400 billion stars, or even more. There are three kinds of galaxies.

Galaxies. Galaxies are the cosmic metropolises in which stars are born, live, and ultimately die. There are as many as a trillion galaxies in the observable universe, yet each is as unique as a snowflake. Our own Milky Way Galaxy contains several hundred billion stars. Stars are seldom found alone in the universe When galaxies form and then evolve, the chemical composition of their stars and gas changes. The mass-metallicity relationship of galaxies is a key to understanding the physics of galaxy formation and evolution in an expanding universe dominated by dark matter and dark energ. Emeritus facuty member Rolf Kudritzki has pioneered a new approach.

The identification of other galaxies, or independent stellar systems, goes back to 1924, when Edwin Hubble found Cepheid variables in the nearby galaxies Messier 33 and Messier 31. Application of the Period‐Luminosity Relation for these variables in the Magellanic Clouds established that these were objects outside the confines of the Milky Way and of sizes comparable to it

THE PROPERTIES OF GALAXIES . Freshman Seminar Project. The primary goal of this project is to examine the properties of galaxies from the database of a large, homogeneous galaxy catalog. We will use J. Huchra's redshift catalog galaxies selected from the 2MASS (2 Micron All-Sky Survey) catalog. The catalog here is a flux (magnitude) limited. Until a couple of weeks ago, the established count for galaxies was about 200 billion galaxies. Jacinta studies distant galaxies like those shown in this image from the Hubble Space Telescope. The Milky Way is only one of the 30 galaxies forming the Local Group of galaxies that measures about 5 million light years across. The Milky Way has three galaxies satellites: Sagittarius Dwarf Elliptical Galaxy, Large Magellanic Cloud and Small Magellanic Cloud.The closest one is the Sagittarius Dwarf Elliptical Galaxy, discovered in 1994 and located only 80,000 light years away Seyfert Galaxies The key to classifying a galaxy as a Seyfert Galaxy is the presence of broad emission lines from the bright, star-like nucleus. They are often strong radio and infrared sources. The first such active galaxies were discovered in 1943 by Carl Seyfert Galaxies, the birthplaces of countless stars, are typically classified into spiral, elliptical, and irregular (Figure 1). These three types of galaxies have not only different morphology but also different internal characteristics. Spiral galaxies are considered as young and active with lots of newborn stars, while elliptical galaxies seem red.

Spiral galaxies are among the most beautiful and plentiful galaxy types in the cosmos. When artists draw galaxies, spirals are what they first visualize. This is likely due to the fact that the Milky Way is a spiral; as is the neighboring Andromeda Galaxy. Their shapes are the result of long galactic evolution activities that astronomers are still working to understand The jewel-like galaxies pictured here would probably have even more of an eye candy effect in the hardcover format.

The galaxies, each containing a central, bright quasar, are in the process of merging. As the two galaxies in each quasar pair, move closer together, so do their quasars. Hubble caught the action, photographing two quasar pairs that existed 10 billion years ago, during the peak epoch of galaxy close encounters Galaxies got their start nearly 14 billion years ago, with one unimaginably hot, dense and tiny pinpoint. According to the big bang theory, this singularity was the universe in its entirety. Then it exploded, cooling and expanding in the process. Imagine a balled-up piece of paper unfolding into a giant map, and you have a very crude model of. Naturally, things are a little more complicated than this. Filaments themselves move relative to us, and galaxies also move around within filaments, meaning that even galaxies in a non-rotating filament would appear to be moving. To solve this problem, the authors use the redshifts of 213,625 galaxies in 17,181 filaments to work out their line-of-sight velocities (the speed at which each.

Galaxies are a massive collection of stars and dark matter, ranging from a few million stars (dwarf galaxies) to hundreds of billions of stars (giant galaxies). Most galaxies are disk shaped and are tens of thousands of light years in diameter. Galaxies are categorized by three broad shapes - spiral galaxies, elliptical galaxies and peculiar. SBa galaxies have large nuclear bulges and tightly wound spiral arms, while SBc galaxies have small bulges and loosely wound arms (recent evidence suggests that the Milky Way is a SBc galaxy). Irregular: These are small, faint galaxies with large clouds of gas and­ dust, but no spiral arms or bright centers
