Astronomers once thought that these structures were the biggest things out there. In the 1980s, however, scientists realized that groups of galaxy clusters can also be connected by gravity, forming a supercluster, the largest class of objects in the universe. What is the Hercules-Corona Borealis...
NASA's Hubble Space Telescope reveals the supercluster Westerlund 1, home of one of the largest known stars. Westerlund 1-26, a red supergiant, has a radius more than 1,500 times that of the sun.(Image credit: ESA/Hubble & NASA) UY Scuti's large radius does not make it the most mas...
some 163,000 light-years away. It is believed that this star may contain as much as 315 times the mass of the Sun, which presents a conundrum to astronomers since it was believed that the largest stars could only contain 150 solar masses. The answer to this is that ...

Astronomers interpret this motion to mean that the universe itself is expanding; on the very largest scales, the distances between galaxies grow with time. This means that in the past, the universe was smaller, hotter and denser than it is today. Einstein's theory of general relativity allows...
Our Galaxy is the Milky Way and estimated at 100,000 light-years across. The furthest galaxy that we have discovered so far is GN-z11 which is located in the constellation of Ursa Major and is over 32 billion light-years away. The largest known Galaxy is IC 1101, discovered by Sir...
What is the largest star in our galaxy? What is the closest galaxy to the Milky Way? What is the life cycle of a star cluster like? Which star cluster is closer: TUC 47 or Palisades? What is the biggest star in the universe?
2.In some ways, it's still an appropriate term because traveling to another galaxy would be extremely difficult, impractical, or downright impossible due to the vast distances involved. 3.Andromeda, the largest galaxy in the Local Group, is one galaxy that can be seen - at...
What is the size of the sun's diameter in kilometers? How old is the the universe? What is bigger than a supercluster? What is the average size of a black hole? How many galaxies are in the Virgo Supercluster? How massive are the largest known galaxies?
