Black Hole

Gaia BH2, one of the closest black holes to Earth ever detected, sits 3,800 light-years away in the constellation Centaurus. Here, the galaxy Centaurus A shines brightly.

(Image credit: NASA/JPL-Caltech) For the first time, astronomers have spotted a jet blasting from the core of a distant galaxy that has changed directions. About 1% of the…

When the immense Arecibo radio telescope in Puerto Rico collapsed in 2020, it left gaping holes in astronomy. Now, a team from the California Institute of Technology (Caltech) hopes to address some of the gaps with a very different instrument: a tightly packed array of relatively inexpensive radio dishes that…

In a distant galaxy, a supermassive black hole spewing radiation at near light speed has shifted its angle by a whopping 90 degrees to point directly toward Earth — a sharp turn that's puzzling physicists. Active galactic nuclei (AGN) are the hungry black holes at the cores of many other…

In 2022 on October 8, an intense pulse of gamma-ray radiation swept through our solar system. The source, dubbed GRB 221009A for its discovery date, turned out to be the brightest gamma-ray burst (GRB) ever recorded. GRB 221009A lasted over 300 seconds. According to astronomers, such “long-duration” GRBs are the…

On October 9, 2022, an intense pulse of gamma-ray radiation swept through our solar system, overwhelming gamma-ray detectors on numerous orbiting satellites, and sending astronomers on a chase to study the event using the most powerful telescopes in the world. The new source, dubbed GRB 221009A for its discovery date,…
