Astronomers discover vast ancient galaxies, which could shed light on dark matter
Astronomers have used the combined power of multiple astronomical observatories around the world and in space to discover a treasure trove of previously unknown ancient massive galaxies. This is the first multiple discovery of its kind, and such an abundance of this type of galaxy defies current models of the universe. These galaxies are also intimately connected with supermassive black holes and the distribution of dark matter.
