Galaxy clusters typically contain hundreds to thousands of galaxies.

Elliptical galaxies are the most common type of galaxy found in galaxy clusters.

Galaxy clusters typically have masses ranging from 10^14 to 10^15 solar masses.

Galaxy clusters typically have diameters of a few megaparsecs.

The hottest gas found in galaxy clusters is X-ray gas, which can reach temperatures of millions of degrees.

The primary source of energy in galaxy clusters is gravitational energy, which is released as galaxies fall towards the center of the cluster.

Abell 2029 is the most massive galaxy cluster known to date, with a mass of approximately 10^16 solar masses.

The Virgo Cluster is the closest major galaxy cluster to the Milky Way, located approximately 50 million light-years away.

The Sunyaev-Zel'dovich effect is responsible for the blue tint of some galaxy clusters, caused by the scattering of cosmic microwave background radiation by hot electrons in the cluster gas.

The Hercules-Corona Borealis Great Wall is the largest known structure in the universe, stretching over 10 billion light-years.

Dark matter is thought to play a crucial role in holding galaxy clusters together, as the visible matter alone is not sufficient to explain the observed gravitational forces.

In the distant future, galaxy clusters are expected to merge with other clusters, forming even larger structures.

Minor mergers, where a smaller cluster merges with a larger one, are the most common type of galaxy cluster merger.

The Milky Way is part of a small galaxy cluster called the Local Group, which contains about 50 galaxies.

The Sloan Great Wall is the largest galaxy cluster in the observable universe, stretching over 1.37 billion light-years.
