The small galaxy Was 49b is being eaten by the much larger galaxy Was 49a. But 49b will not go gently into that good night: It's blasting out a lot of radiation, because at its heart is a hugely outsized black hole.
New observations indicate that in a (relatively) nearby star cluster, there's a black hole, physically ripping material off a white dwarf and eating it. Called 47 Tuc X9, this is the closest a star has ever been seen orbiting a black hole.
Black holes are one of the most fascinating miracles in nature, and hold the potential promise of hopping across (or between) universes. There’s just one problem — we don’t exactly know how to actually survive traveling through a wormhole. Until now. Maybe.
