More images of 3C295
The NASA Chandra X-ray Observatory image of the distant galaxy
3C295 shows an explosive galaxy enveloped by a vast cloud of
fifty million degree gas. The gas cloud, which is visible only
with an X-ray telescope, contains more than a hundred galaxies
and enough material to make a thousand more. The galaxies are
too cool to be visible in X rays. Roughly two million light
years in diameter, the cloud and its cluster of galaxies are
among the most massive objects in the universe. It is so distant
that we see it as it was five billion years ago.
