Title : Hot gas enveloping the extremely distant galaxy 3C294
Caption :
This Chandra image shows hot gas enveloping the extremely distant galaxy known as 3C294. Astronomers believe this is the most distant cluster of galaxies ever detected in x-rays, capturing it when the universe was only 20 percent of its current age. The existence of such a faraway cluster may have important implications for how the universe evolved.
