Hubble sees Comet Galaxy being ripped apart by galaxy clusterThe NASA/ESA Hubble Space Telescope, in collaboration with several other ground- and space-based telescopes, has captured a galaxy being ripped apart by a galaxy clusterÂs 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.
