A black hole is burping out the remnants of a star it ripped apart and ate years ago in a type of tidal disruption event that is like nothing astronomers have ever seen.

Where better to grow plants that on the Moon? Well, lots of places, to be honest, including almost everywhere on planet Earth. But that’s not going to stop people from trying to do so – especially as plants grown in space are going to be critical to any long-term space exploration program, and the Moon seems as good a place as any to do that. So the idea of a team of scientists from Australia, Israel, South Africa, and the US to grow some plants on the Moon by 2025 might not be as far-fetched as it seems.
The two most conspicuous star patterns whirling in their nightly course in the northern skies are the Big Dipper and the "W" of Cassiopeia the Queen.
During the late evening hours of Friday (Oct. 14), Mars will rendezvous with the moon in the night sky.
Scientists have uncovered a new mystery about Uranus' rings buried deep in data from NASA's iconic Voyager 2 mission.
A Falcon 9 rocket is scheduled to launch Eutelsat's Hotbird 13F communications satellite Friday (Oct. 14) during a 116-minute window that opens at 11:26 p.m. EDT (0326 GMT on Oct. 15).
These moonless evenings open the sky for good constellation spotting and deep-sky probing.
Pegasus flies high. Draco eyes Vega. And it's time for the Orionid meteors.
Mississippi River, one of the longest rivers in North America, is featured in this multi-temporal radar image captured by the Copernicus Sentinel-1 mission.
Seeing how a spacecraft dies
That’s no moon … wait … yes, it is, and more!
Puerto Rico's iconic radio telescope, which collapsed in 2020, won't be rebuilt, although the site will see a new education center open next year.
China launched an environmental satellite into space Wednesday (Oct. 13) amid a surge of rocket activity.
If the next launch attempt of the Artemis I mission goes as planned, it should be a spectacular sight.
Originally predicted by Einstein’s Theory of General Relativity, black holes are the most extreme object in the known Universe. These objects form when stars reach the end of their life cycle, blow off their outer layers, and are so gravitationally powerful that nothing (not even light) can escape their surfaces. They are also of interest because they allow astronomers to observe the laws of physics under the most extreme conditions. Periodically, these gravitational behemoths will devoir stars and other objects in their vicinity, releasing tremendous amounts of light and radiation.
The real-world mockup of the fictional "Darkstar" hypersonic jet seen in the opening sequence of the 2022 film "Top Gun: Maverick" is on display this weekend in Southern California.
When the James Webb Space Telescope (JWST) launched, one of its jobs was studying galactic formation and evolution. When we look around the Universe, today’s galaxies take the shape of grand spirals like the Whirlpool galaxy and giant ellipticals like M60. But galaxies didn’t always look like this.
NASA's iconic new observatory has spotted surprising compounds around supermassive black holes.
An innovative method enables astronomers to gauge the size and shape of a distant asteroid — and potentially any km-scale object in the solar system.
