NASA's James Webb Space Telescope recently zeroed in on the Bullet Cluster—delivering highly detailed images that show a ...

Astronomers have been mapping vast cosmic structures for decades, from galaxy clusters to immense superclusters. But now, researchers have identified what they say is officially the largest known ...

Now, an international team of researchers reports that even Laniakea is actually part of an even larger “basin of attraction,” or BOA, known as the Shapley Concentration (named after U.S ...

Astronomers have found that our galaxy, the Milky Way, may be a tiny part of an even larger local structure than we thought. The research, if confirmed by further observations and studies, may be ...

There are even bigger and more populous groups, called galaxy clusters. The nearest big one is the Virgo Cluster, with well over 1,000 galaxies in it, located about 50 million light-years from us.

As they continued to map the observable universe, astronomers looking at 400 elliptical galaxies noticed that they were moving towards something we cannot see, as it is in the "Zone of Avoidance ...

Laniakea comprises four supercluster branches totaling over 500 groups and clusters with more than 100,000 individual galaxies. The massive, tangled complex stretches for over half a billion light ...
