galaxy - April 17 2019 6 min read sgo777 Galaxies are sprawling systems of dust gas dark matter and anywhere from a million to a trillion stars that are held together by gravity Nearly all large Galaxy Evolution In 2004 NASA released the Hubble Ultra Deep Field This image of a small part of the constellation Fornax contains around 10000 galaxies some of which existed 13 billion years ago less than 800 million years after the big bang Snapshots like these allow scientists to study galaxies at different evolutionary stages Galaxy Definition Formation Types Properties Facts 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 youre seeing other stars in the Milky Way If its really dark far away from lights from Galaxiesfacts and information National Geographic A galaxy is a system of stars stellar remnants interstellar gas dust and dark matter bound together by gravity 12 The word is derived from the Greek galaxias γαλαξίας literally milky a reference to the Milky Way galaxy that contains the Solar System Learn how galaxies form and evolve over time and how they are shaped by black holes mergers and gravitational lensing Explore the research topics and projects of Center for Astrophysics scientists on galaxy structure and history Types of Galaxies Scientists sometimes categorize galaxies based on their shapes and physical features Other classifications organize galaxies by the activity in their central regions powered by a supersized black hole and the angle at which we view them Spiral Galaxies Our Milky Way is one example of a broad class of galaxies ViewSpace ViewSpace

Formation and Evolution Center for Astrophysics Galaxy groups and clusters are collections of galaxies bound together by gravity They are building blocks for the largerscale structures of the universe The Hubble Space Telescope captured this image called the Hubble Ultra Deep Field in 2004 by combining 800 images with a cumulative exposure of 113 days It contains around 10000 galaxies Galaxies Images NASA Science What is a galaxy Live Science Milky Way Galaxy large spiral system consisting of several hundred billion stars one of which is the Sun It takes its name from the Milky Way the irregular luminous band of stars and gas clouds that stretches across the sky as seen from Earth Although Earth lies well within the Milky Way Galaxy sometimes simply called the Galaxy Galaxies are vast cosmic islands of stars gas dust and dark matter held together by gravity Hubbles keen eye has revealed intricate details of the shapes structures and histories of galaxies whether alone as part

Galaxies the cosmic cities of the universe explained by Galaxy Types ScienceNASA Galaxy Basics Galaxies consist of stars planets and vast clouds of gas and dust all bound together by gravity The largest contain trillions of stars and can be more than a million lightyears across The smallest can contain a few thousand stars and span just a few hundred lightyears Most large galaxies have supermassive black holes at An even closer galaxy named the Canis Major Dwarf is located a mere 25000 lightyears from Earth but it has become so disrupted by the Milky Way that many of its stars are already strewn across Galaxy Evolution ScienceNASA Galaxies Collisions Types and How Theyre Made Space Whats a galaxy All you need to know EarthSky Galaxies are composed of stars dust and dark matter all held together by gravity Astronomers arent certain exactly how galaxies formed After the Big Bang space was made up almost entirely of Large Scale Structures NASA Science Galaxy 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 Virtually all galaxies appear to have been formed soon after the universe began and they pervade all space that is viewable by modern telescopes The galaxys spiral arms are part of this disk where the youngest and brightest stars of the galaxy live Astronomers study the populations of stars and material between them to understand the evolution of the galaxy The most massive part of the Milky Way and any galaxy is the halo which is a roughly
