Astronomers have discovered behavior by a jet from a giant black hole that has never been seen before. Using NASA's Chandra X-ray Observatory they have observed a jet that bounced off a wall of gas and then punched a hole in a cloud of energetic particles. This behavior can tell scientists more about how jets from black holes interact with their surroundings. The discovery was made in Cygnus A, a large galaxy in the middle of a cluster of galaxies about 760 million light years from Earth. Chandr... ASTRO WATCH · 5 months
