galaxy clusterhot plasmaplasma propertiesClusters of galaxies are the largest organized structures in the Universe. They are important cosmological probes, since they are large enough to contain a fair sample of the materials in the Universe, but small enough to have achieved dynamical equilibrium. ...
his artist's impression shows quasars scattered throughout the cosmic web in the early universe. (Image credit: ESO/M. Kornmesser') A spooky new image shows a web of bright galaxies aligned in the largest structures ever discovered in the universe. Scientists working with a telescope in ...
Galaxy clusters, often referred to as the “big cities” of the universe, are populated by giant elliptical galaxies that have stopped forming stars and completed their growth. Despite extensive research, the exact mechanism behind this shutdown of star formation remains uncertain. In a groundbreakin...
We've known for a while about the large-scale structure of the Universe. Galaxies reside in filaments hundreds of millions of light-years long, on a backbone of dark matter. And, where those filaments meet, there are galaxy clusters. Between them are massive voids, ...
An illustration of galaxy superclusters and cosmic voids, similar to the structure of the BOSS Great WallScience Photo Library/Corbis The English language has a few limitations. One such problem is describing size—words like big, humongous and immense don’t come close to describing the objects...

Galaxy clusters, known as the largest self-gravitating objects in the universe, are home to a vast expanse of high-temperature gas. This gas emits brilliant X-rays, making these clusters visible. When these colossal clusters merge, it culminates in an astronomical event of unmatched magnitude,...
If so, it would be reasonable to believe that life springs up in the universe quite easily once there are the necessary ingredients, and that life might be found throughout our galaxy (银河系), and the universe. If life were found on Europa. how might it change your view of the ...
discovered what may be the largest black hole known to date.The black hole has a mass (量) of about 30 billion suns and sits at the center of a galaxy(星系), which is hundreds of millions of light-years from the Earth.Black holes are one of the most powerful forces in the universe...
Most stars of this type are between 200 and 800 times the radius ofour Sun. The very largest stars in our galaxy, all red supergiants, are about 1,500 times the size of our home star. Because of their immense size and mass, these stars require an incredible amount of energy to sustai...
