What is the COSMOS 1526561 galaxy?
The COSMOS 1526561 galaxy (one of the galaxies in the COSMOS survey) is a spiral galaxy 7500 million light-years from Earth in the Sextans constellation, and is 100,000 light-years in diameter, and contains about 100 billion stars.
What is the COSMOS 2607238 galaxy?
The COSMOS 2607238 galaxy (one of the galaxies in the COSMOS survey) is a barred spiral galaxy 6300 million light-years from Earth in the Sextans constellation, and is 100,000 light-years in diameter, and contains about 100 billion stars.
Is cosmos the same as galaxy?
No. 'Cosmos' is another word for 'universe'. The cosmos contain millions of galaxies.
What is the COSMOS 397553 galaxy?
The COSMOS 397553 galaxy (one of the galaxies in the COSMOS survey) is a barred spiral galaxy 6000 million light-years (redshift of 0.66) from Earth in the Sextans constellation, and is 100,000 light-years in diameter (same size as the Milky Way), and contains about 100 billion stars (same number of stars as the Milky Way).
How many galaxies in the cosmos?
There are about 1011 (a 1, followed by 11 zeroes) galaxies in the known Universe. It is not currently known how much bigger the entire Universe is, compared to the known Universe.
What is the COSMOS 1177059 galaxy?
The COSMOS 1177059 galaxy (one of the galaxies in the COSMOS survey) is an elliptical galaxy 7700 million light-years (redshift of 0.97) from Earth in the Sextans constellation, and is 60,000 light-years in diameter (about 1.7 times smaller than the Milky Way), and contains about 40 billion stars (40 percent of the Milky Way's stars).
What is the COSMOS 786560 galaxy?
The COSMOS 786560 galaxy (one of the galaxies in the COSMOS survey) is a spiral galaxy 6000 million light-years (redshift of 0.66) from Earth in the Sextans constellation, and is 120,000 light-years in diameter (1.2 times larger than the Milky Way), and contains about 200 billion stars (200 percent of the Milky Way's stars).
What is the COSMOS 781155 galaxy?
The COSMOS 781155 galaxy (one of the galaxies in the COSMOS survey) is a spiral galaxy 7000 million light-years (redshift of 0.83) from Earth in the Sextans constellation, and is 120,000 light-years in diameter (1.2 times larger than the Milky Way), and contains about 200 billion stars (200 percent of the Milky Way's stars).
What is the COSMOS 1161898 galaxy?
The COSMOS 1161898 galaxy (one of the galaxies in the COSMOS survey) is a barred spiral galaxy 5300 million light-years (redshift of 0.54) from Earth in the Sextans constellation, and is 90,000 light-years in diameter (almost the same size as the Milky Way), and contains about 100 billion stars (the same number of stars as the Milky Way). It emitted its light 5300 million years ago, when the universe was 8400 million years old.
Will the Sloan Digital Sky Survey map and redshift all 100 billion galaxies in the observable universe?
It will be impossible for the Sloan Digital Sky Survey to map and redshift all 100 billion galaxies in the observable universe.
What is the theory that the galaxies prove that the cosmos is not steady and unchanging?
The theory that suggests galaxies demonstrate the cosmos is not steady and unchanging is known as the Big Bang Theory. This theory posits that the universe began from a singular, extremely hot and dense state approximately 13.8 billion years ago and has been expanding ever since. Observations of distant galaxies show that they are moving away from us, which supports the idea of an expanding universe. This expansion indicates that the cosmos is dynamic and has evolved over time, rather than being static.
How can astronomers survey at least 100 billion galaxies to make a 3D map of the observable universe?
No, because it will be impossible for astronomers to survey at least 100 billion galaxies (each with 100 billion stars) to make a 3D map of the observable universe.
