Description : (La description de cette image n'existe qu'en anglais)
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.
