Black holes

The spiral could be seen drifting northwards over South Island at 7:30 p.m. local time on Sunday.

Black holes are regions of spacetime where gravity is so extreme that nothing, not even light, can escape.

Black holes are regions of spacetime where gravity is so extreme that nothing, not even light—the fastest thing in the universe—can escape.

A newly detected isolated black hole is thought to be one of millions that wander invisibly through our galaxy.

The supermassive black hole, which weighs as much as 4.3 million suns, is only the second ever to be imaged.

Scientists appear to be preparing to make an exciting reveal about Sagittarius A*, the black hole at the center of the Milky Way.

The announcement could feature an important discovery about our galaxy's supermassive black hole, Sagittarius A*.

One of the biggest questions in science, first posed by Stephen Hawking, has been solved without re-writing the laws of physics, according to a team of experts.

The bubbles, which extend over 36,000 light-years, are being driven by energetic outflows from its supermassive black hole.

The new model could explain how wormhole-like structures in black holes allow information to escape back into the Universe, potentially solving a long-standing paradox.

Astronomer Dietrich Baade told Newsweek: "Stellar vampires do not suck blood but gas, but like others vampires, they can substantially weaken their victims."

The two colossal black holes, 9 billion light-years from Earth, orbit each other once every two years and will have a highly energetic collision when they meet.

The black hole is stealing material from a companion star, in a process that could show how black holes get a kick from supernova explosions that form them.

The black hole is thought to have become separated after its stellar neighbor went supernova and exploded, kicking it into space.

Astronomers found that parts of the galaxy where stars are born were being protected from these powerful outflows thanks to its structure.

The unsettlingly large number of these cosmic monsters means there could be billions in each and every galaxy.

The students came across the highly energetic cosmic event while scanning through decades-old telescope data.

From imaging black holes, rovers on Mars, chimeric embryos, and coming up with solutions to plastic pollution, 2021 has been an important year for science.

The supermassive black hole at the heart of the Centaurus A galaxy blasts out powerful radio jets as it ejects material into space at near light speed.

The powerful explosive event, nicknamed "The Cow," was 100 times brighter and faster than a regular supernova.

The NASA/ASI project will tell us more about some of the most violent objects in the universe and what happens as gravity and magnetism are pushed to extremes.

The Imaging X-ray Polarimetry Explorer (IXPE) spacecraft will observe polarized light from powerful objects in the cosmos, such as black holes and neutron stars.

A source of speculation since the 19th Century, a new study may reignite the debate about a planet that could be lurking at the edge of our Solar System.

The discovery by astronomers could help us better understand how some black holes grow to such tremendous sizes.

The results could help astronomers understand violent cosmic events in which black holes devour stars and launch powerful jets of material at near light speed.

Scientists are currently unable to explain these mysteries, but are working hard to unravel them.

The method could help astronomers hunt for black holes much closer to home.

The growth of massive merging black holes with masses over 40 times that of the sun could be linked with the accelerating expansion of the Universe in a "cosmological coupling."

Researchers may now understand how the supermassive black hole at the heart of M87 launches a jet of plasma spreading across thousands of light-years.

The material that billows out from feeding supermassive black holes stretches for thousands of light-years "impacting anything that stands in their way."
