Smaller black holes tend to attract less material, making them naturally dimmer. Chandra would miss many of these faint ...

Supermassive black holes lurk all throughout the known universe, but catching one in the act of devouring its cosmic dinner doesn't happen all that often. In fact, unless a black hole is actively in ...

On a scale that stretches human intuition, a distant supermassive black hole has hurled matter into space at 134 million ...

Black holes are often considered terrors of the known universe. Supermassive black holes are regions of space where the pull of gravity is so intense that even light doesn't have enough energy to ...

The Hubble Space Telescope captures an image of a supermassive black hole that is not at the center of its galaxy. Credit: NASA / ESA / STScI / Yuhan Yao / Joseph DePasquale Using NASA's Hubble Space ...

Primordial black holes that formed during the earliest moments of the universe could have swollen quickly to supermassive sizes, complex cosmological simulations have revealed. The discovery could ...

Astronomers have detected the first tidal disruption event (TDE), designated AT2024tvd, occurring 2,600 light-years outside its host galaxy's core, exhibiting intense, rapidly evolving radio signals.

Back in 2024, a system set up to identify objects that suddenly brighten found something unusual. Unfortunately, the automated system that was supposed to identify it couldn’t figure out what it was ...

Scientists may have finally uncovered the mystery behind ultra-high-energy cosmic rays — the most powerful particles known in the universe. A team from NTNU suggests that colossal winds from ...

Astronomers have spotted the largest and most distant flare ever observed from a supermassive black hole. Nicknamed “Superman,” the flare originated 10 billion light-years from Earth, and at its peak, ...

One of the most notable aspects about our planet—if observed from the outside—is that it spins. Earth’s spin defines our days, setting the fundamental rhythm of life on our world. The moon spins, too.

When black holes emerge out of hiding to feast on their prey and some type of matter is sucked into their celestial maw, they begin to glow brightly. The events, dubbed “extreme nuclear transients,” ...
