Clues to growth of colossus in Coma cluster of galaxies

Astronomers have discovered enormous arms of hot gas in the Coma cluster of galaxies. These features, which span at least half a million light years, provide insight into how the Coma cluster has grown through mergers of smaller groups and clusters of galaxies to become one of the largest structures in the Universe held together by gravity.
