Using the Very Large Array (VLA), astronomers have performed radio observations of a galaxy cluster Abell 2744, nicknamed ...

The Bullet Cluster, named for its distinctive shape, has long been considered a smoking gun for the existence of dark matter ...

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 ...

Over large distances, galaxies can clump together into clusters, ... such as the Sloan Great Wall or the Laniakea supercluster, which were the previous largest structures known in the universe. ...

Since the confirmation of its existence in 2014, the Laniakea supercluster was thought to be our ultimate cosmic neighborhood—home to the Virgo supercluster, the local cluster, and the good old ...

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 ...

The Virgo Cluster and the Local Group are part of the Laniakea Supercluster, which may have more than 100,000 galaxies in it and stretches for 500 million light-years.

Where it is: El Gordo galaxy cluster, around 7 billion light-years from Earth. Why it's so special: For the first time, researchers have sketched out the invisible magnetic field of a gigantic ...

Astronomers noticed 400 galaxies, ... "Local flows within the region converge toward the Norma and Centaurus clusters in good ... We propose that we live in the Laniakea Supercluster of galaxies." ...

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 ...

The dipole repeller sounds like the premise of a bad sci-fi movie: There's some mysterious entity, beyond the boundaries of our galaxy, that is pushing against us with incredible force.
