Black holes - the supermassive gravitation forces at the center of most galaxies - actually spend much of their time dormant, or essentially asleep. Astronomers have now spotted one not only ...

A lthough we know that supermassive black holes (millions of times the mass of our sun) lurk at the center of most galaxies, their very nature makes them difficult to spot and study. In contrast ...

From Boring to Bursting: Giant Black Hole Awakens Apr. 11, 2025 — Astronomers are investigating the longest and most energetic bursts of X-rays seen from a newly awakened black hole. Watching ...

Artist’s impression of the accretion disc around the massive black hole Ansky and its interaction with a small celestial object Disclaimer: AAAS and EurekAlert! are not responsible for the ...

"This pushes our models to their limits and challenges our existing ideas about how these X-ray flashes are being generated." ...

Major Black holes are some of the most extreme objects in the cosmos. These massive, extraordinarily dense objects have such strong gravity that they suck in anything which comes to close to them ...

In a galaxy 300 million light-years away from Earth, a once-quiet black hole has woken up. Astronomers became aware of this galaxy in the Virgo constellation when it abruptly began to light up in ...

Black holes are regions in space where an enormous amount of mass is packed into a tiny volume. This creates a gravitational pull so strong that not even light can escape. They are created when giant ...

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.
