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)
