Abell 2667 is a galaxy cluster. It is one of the most luminous galaxy clusters in the X-ray waveband known at a redshift about 0.2 and is a well-known gravitational lens.
On 2 March 2007, a team of astronomers reported the detection of the Comet Galaxy in this cluster. This galaxy is being ripped apart by the cluster's gravitational field and harsh environment. The finding sheds light on the mysterious process by which gas-rich spiral-shaped galaxies might evolve into gas-poor irregular or elliptical-shaped galaxies over billions of years.
