Astronomers have uncovered a black hole that may have sparked the birth of stars over a phenomenal distance of more than a million light years and across multiple galaxies.
Scientists have found stars forming at a furious rate in the Phoenix galaxy cluster. The supermassive black hole in the center of galaxy clusters usually stifles star formation, but the one in Phoenix is not.
When two pairs of galaxy clusters collide, the result is not four separate objects, but one giant galaxy cluster.

Astronomers found X-ray bursts repeating about every nine hours coming from the supermassive black hole at the center of the galaxy GSN 069.
Over its two decades in space, Chandra X-ray Observatory has captured many spectacular images of cosmic phenomena. But perhaps its most iconic is the supernova remnant called Cassiopeia A.
Found at a time only about 850 million years after the Big Bang, this black hole could help us better understand an important epoch in the history of the Universe.
