Normally black holes do not emit light. But when X-ray is passed to it, it lightens up. Star Heida is the one that is recently been discovered through X-rays. The most astonishing fact about it is its location not present at the center of galaxy like other black holes. Furthermore it is a recoiling supermassive black hole. Recoiling black holes are a good source for research in finding how supermassive black holes are formed at the center of galaxies. So this black hole will be a lot worth. There is more possibility of finding more supermassive recoiling black holes. Researchers are now going to use NASA’s Chanda satellite to find more.
