Abell 370

Abell 370 is a massive galaxy cluster located about 4 billion light-years away in the constellation Hydra. It contains thousands of galaxies bound by gravity, with a significant amount of dark matter and hot gas. Its most remarkable feature is the “The Mushroom” gravitational lens, which magnifies and distorts the light from more distant galaxies behind it. This effect allows astronomers to study galaxies that would otherwise be too faint to see, providing valuable insights into the universe's structure, dark matter, and galaxy evolution. Abell 370 is a key target for understanding the large-scale cosmos.
