Astronomers have imaged the twisted jet structure in the core of the galaxy OJ 287 for the first time – evidence of two supermassive black holes in the process of merging.

A giant spiral galaxy with powerful jets from a black hole has shocked scientists, because it shows that even galaxies like ours can release dangerous radiation at some point.

Artist's rendering of the heaviest pair of supermassive black holes: Using archival data from the Gemini North Telescope, a team of astronomers has measured the heaviest pair of supermassive black holes ever found. The merger of two supermassive black holes is a long-predicted but never-observed phenomenon. This pair provides insight into why such an event seems so unlikely in the universe. Credit: NOIR LAB

Impressively, a pair of supermassive black holes (top left) emit gravitational waves that propagate through the fabric of space-time. These gravitational waves compress and stretch the trajectories of radio waves that emit pulsars (in white). By carefully measuring the radio waves, a team of scientists recently discovered for the first time the gravitational wave background of the universe.
