Astronomers have spotted a surprising number of quasars with jets launched within a couple of decades.
Gravitational-wave scientists have unveiled their latest catalog of events, revealing a surprising number of massive black holes.
This year’s award goes to three researchers who played key roles in developing the theoretical and observational evidence for black holes.
Astronomers think they’ve detected a flash created by the merger of two black holes.
Astronomers have caught a black hole colliding with a mysterious companion that might be either one of the most massive neutron stars or the smallest black hole ever detected.
Calculations suggest how black holes have amassed mass and predict what the black holes’ spins should be if this picture is correct.
Observations from the worldwide network of radio telescopes show the fire hose of plasma shooting from a distant galaxy does something strange near its source.
Detailed calculations reveal a surprise about how black holes bend light around themselves, opening a new possibility for future observations.
Two studies support the suspicion that our galaxy’s black hole had one or more outbursts a few million years ago.
