Ansky, a once-dormant black hole, is now emitting powerful X-ray bursts, giving scientists a rare chance to study its activity in real time.

The black hole at the heart of galaxy SDSS1335+0728, located 300 million light-years away, was quiet for decades as it consumed little matter and was in a dormant state. But recently it suddenly lit ...

the galaxy started shining brightly. But since 2024, that black hole the astronomers nicknamed “Ansky” started producing X-ray bursts at regular intervals — almost as if Ansky was stretching, then ...

For more than eight hours last fall, the Chandra X-Ray Observatory stared at a nondescript galaxy 240 million light-years away. In that time, one of the detectors intercepted exactly four X-ray ...

A Michigan State University researcher saw X-rays coming from a black hole using the NASA Chandra X-Ray Observatory telescope. "Every large galaxy has a supermassive black hole, but the exact ...

M16, also known as the Eagle Nebula, is a young star-forming region in the Serpens constellation, famously home to the "Pillars of Creation" captured by the Hubble Space Telescope. NGC 3627 is a ...

A massive black hole at the heart of a galaxy in the Virgo constellation is waking up, shooting out intense X-ray flares at regular intervals that have puzzled scientists, a study said Friday.
