Abell 370 is a galaxy cluster located about 4 billion light-years away in the constellation Fornax. It is notable for its strong gravitational lensing effects, which occur when the cluster's mass bends the light from more distant galaxies, creating distorted and magnified images. This cluster contains hundreds of galaxies and is part of the Abell catalog, a collection of galaxy clusters compiled by astronomer George Abell in the 1950s. Abell 370 serves as an important target for studying dark matter and the large-scale structure of the universe.
