We could say NASA has just discovered a never-before-seen black hole, but it might also be true to say a new black hole just threw up signal flares and shouted at us to discover it.
A rare X-ray nova–a release of X-ray energy–was first caught by NASA’s Swift telescope in September. Scientists focused in on it and unraveled a story: the black hole formed a binary system with a nearby star, sucking in gas, then eventually releasing it. It’s a rare event–the first one the Swift satellite has ever seen.
