Beautiful astronomical photo captured by Chandra, I like it for the swirls of colour




Chandra excels at capturing chaos. An astronomical feature called Cas A, in the constellation Cassiopeia, is a blast of debris expanding at millions of miles an hour; it was fired from a supernova that became visible on Earth only about 300 years ago.
