Astronomers have uncovered clues to a red giant’s chaotic past by detecting subtle stellar vibrations that hint at a long-ago collision and an unexpectedly rapid spin. Astronomers at the (IfA) have pi ...

Theoretical physicists have long debated the possible existence of wormholes, which are mathematically possible, but no evidence points to their physical existence. One theory suggests that these ...

UCLA astronomers report the discovery of a remarkable star that orbits the enormous black hole at the center of the Milky Way Galaxy in a blistering 11.5 years — the shortest known orbit of any star ...

Simply put, a black hole is a region of space-time where gravity is so strong that nothing can escape from it. This includes light, which travels at the cosmic speed limit of 186,000 miles per second.

In the world of black holes, there are generally three size categories: stellar-mass black holes (about five to 50 times the mass of the sun), supermassive black holes (millions to billions of times ...

Black holes are well known for swallowing everything around them, which is probably why they get talked about so often. On the flip side, white holes are their mysterious opposite. These theoretical ...

Black holes have traditionally been viewed as powerful and destructive forces in the cosmos, capable of consuming anything that ventures too close into their gravitational pull. Yet, a ground-breaking ...

Scientists have tapped into gravitational lensing and stellar dynamics to confirm the existence of a black hole with 36 billion solar masses. A bold new proposal envisions launching laser-propelled ...

The younger black hole, the product of a cataclysmic cosmic event known as a black hole merger, was first spotted in 2019. Now, about 6 years later, a team of international researchers led by the ...

Scientists say they detected the largest-ever merger of two black holes, forming one that is 225 times the mass of the sun, adding that the new discovery "pushes the limits of" how astronomers ...

A mysterious ring of light is thought to surround every black hole, and Alex Lupsasca wants to glimpse one for the first time. The tendril-thin halo, called a photon ring, has the power to reveal ...

When scientists discovered an enormous black hole thousands of light-years from where it ought to be in space, they knew they had a cosmic oddity on their hands. NASA's Hubble Space Telescope showed a ...
