WASHINGTON, Feb 12 (Reuters) - The formation of a black hole can be quite a violent event, with a massive dying star blowing up and some of its remnants collapsing to form an exceptionally dense ...

Scientists have named newly detected merging supermassive black holes after ’Lord of the Rings’ locations, using gravitational wave data and quasar observations to map their mergers.

Recent observations suggest that 'runaway' black holes are tumbling through the cosmos. Building on decades of theory, the discovery adds a remarkable new chapter to the story of the universe.

Supermassive black holes rarely travel alone. Most large galaxies hide one at the center, and when galaxies collide, the two ...

A massive star 2.5 million light-years away simply vanished — and astronomers now know why. Instead of exploding in a supernova, it quietly collapsed into a black hole, shedding its outer layers in a ...

In 2014, a NASA telescope observed that the infrared light emitted by a massive star in the Andromeda galaxy gradually grew brighter. The star glowed more intensely with infrared light for around ...

When the researchers calculated the black hole's energy output, they were met with an additional surprise. It's about equal to the energy released by a gamma-ray burst (GRB). Since GRB are the ...

Scientists say an ultra-powerful neutrino once thought impossible may be explained by an exotic black hole model involving a so-called “dark charge.” ...

A “disappearing” star in the Andromeda galaxy is the closest and best candidate for a newborn black hole that astronomers have ever seen ...

In my January 23, 2026, “The Universe” column, I wrote about some of the biggest bangs the universe has to offer: exploding stars, hiccupping magnetars, stellar disruptions and colliding black holes.

A massive star in the nearby Andromeda galaxy has simply disappeared. Some astronomers believe that it's collapsed in on itself and formed a black hole.

For decades, scientists have theorized that the Milky Way Galaxy’s supermassive black hole, known as Sagittarius A* (Sgr A*), ...
