Black holes are among the most enigmatic and fascinating objects in the universe. These regions of spacetime exhibit such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside them. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
Paramount’s hit sci-fi horror franchise returns in 2027 with more ultrasonic alien invaders.
The techniques used to target the asteroids could also be employed in tracking hazardous asteroids and interstellar objects.
Satellite images revealed the scope of destruction in the south of France where an area larger than the country's capital Paris has been turned into ashes by a massive wildfire.
A newfound supermassive black hole from the dawn of the universe challenges how early cosmic giants formed.
Don’t let the brilliant Moon deter you from enjoying the best meteor shower of the year: the 2025 Perseids.
White dwarfs are remnants of main sequence stars like our Sun that have depleted their hydrogen. Their lives of fusion have come to an end, and they'll simmer with residual heat for trillions of years. Their lifespans are longer than the current age of the Universe.
NASA's Perseverance Mars rover captured a breathtaking panorama of the Red Planet surface depicted in false-color under a blue sky.

SpaceX is gearing up for its first Falcon 9 rocket launch from the West Coast in nine days with a mission to deliver 24 optimized Starlink V2 Mini satellites into a polar, low Earth orbit.
Ahead of Alien: Earth's two-episode premiere, we talked to series creator Noah Hawley and executive producer David W. Zucker.
While moonlight might steal the spotlight, it won't steal the Perseids' show.
New Hubble Telescope imagery of the interstellar interloper comet 3I/ATLAS reveals a dusty coma and the beginning of a tail.
The LaView Galaxy Star Projector posits itself as a premium option, but doesn’t quite live up to the competition.
It’s a disappointing star projector, but the Discovery Space Projector has some nice scientific images of moons and planets.
Scientists have spotted a mysterious mineral on Mars that may be new to science — and could help reveal some Red Planet mysteries.
The MetOp-SG-A1 weather satellite is loaded onto the Ariane 6 launch adapter as part of a mission for the European Space Agency.
The resources tucked away in asteroids promise to provide the building blocks of humanity’s expansion into space. However, accessing those resources can prove tricky. There’s the engineering challenge of landing a spacecraft on one of the low-gravity targets and essentially dismantling it while still remaining attached to it. But there’s also a challenge in finding ones that make economic sense to do that to, both in terms of the amount of material they contain as well as the ease of getting to them from Earth. A much easier solution might be right under our noses, according to a new paper from Jayanth Chennamangalam and his co-authors - mine the remnants of asteroids that hit the Moon.
The full moon rises on Aug. 9; here are the best times to view the Sturgeon Moon.
On May 26th, 2025, the skies were clear on Mars above the Jezero Crater, where the Perseverance rover is exploring the planet's past. The rover's imaging team took advantage of these conditions to capture the 360-degree panoramic photo shown above, which was stitched together from 96 images taken by the rover's Mastcam-Z camera. The photo shows a location called "Falbreen," which shows the rover's tracks (right side) reaching into the far distance towards its previous stop - a rock outcropping named "Kenmore." Also visible are rocks and a sand ripple strewn with hills in the distance that are up to 65 km (40 mi) away.
If detecting exoplanets was easy, then we should have a complete understanding of the planetary system around our nearest stellar neighbour, Alpha Centauri. But we don't, because it's not easy. Alpha Centauri is a triple star system about 4.25 light-years away. The primary star is called Alpha Centauri A, a Sun-like star, and it's in a binary relationship with Alpha Centauri B, another Sun-like star. The third star is a red dwarf named Proxima Centauri, and it's the closest one to us.
