A black hole suddenly flips over

Artist's impression of a hot and dense accretion disk around a black hole, which can be a rich production site of heavy elements. Neutron-rich material is ejected from the disk, enabling the rapid neutron-capture process (r-process). The light blue region is a particularly fast ejection of matter, called a jet, which typically originates parallel to the disk's rotation axis. (National Radio Astronomy Observatory, USA)

There's gold in them thar black holes

Researchers observed bright flares of X-ray emissions, produced as gas falls into a supermassive black hole. The flares echoed off of the gas falling into the black hole, and as the flares were subsiding, short flashes of X-rays were seen – corresponding to the reflection of the flares from the far side of the disk, bent around the black hole by its strong gravitational field.

This image from NASA's Hubble Space Telescope shows the Crab Nebula, the remnant of a supernova explosion with a rapidly spinning neutron star embedded in its center. In October 2017, astronomers detected the merger of two neutron stars some 130 million light-years away. (Getty/NASA)

The black hole next door

Artist's conception shows two merging black holes similar to those detected by LIGO. The black holes are spinning in a non-aligned fashion, which means they have different orientations relative to the overall orbital motion of the pair. LIGO found hints that at least one black hole in the system called GW170104 was non-aligned with its orbital motion before it merged with its partner.
