What's Happening?
Astronomers have captured the deepest-ever images of the massive galaxy cluster Abell 3667, located 700 million light-years from Earth. These images reveal evidence of past galactic mergers and the phenomenon of intracluster light, which enhances understanding of galaxy formation. The research, led by Brown University astronomers, documented a rare moment during a merger of two of Abell 3667’s brightest galaxies, creating a bridge of stars and generating gravitational bursts. This resulted in intracluster light, offering the first optical evidence supporting the theory that Abell 3667 formed from a rapid merger of two galaxy clusters.
