The first black hole that astronomers observed "turning off" just turned back on, releasing jets of hot gas into the cosmos.

In 2018, a galaxy about 270 million light-years away from Earth exhibited a major increase in activity. It quieted down again by 2020 -- only to dramatically increase its output again in 2023. At that ...

Since 2018, we've seen 1ES 1927+654 generate jets in real time and found it may have a lone white dwarf orbiting near the ...
