Scientists have proved that the source of high-energy neutrinos is a special kind of supermassive black holes called blazars.
Far out in the Milky Way, roughly 22,000 light years from Earth, a star unlike any other roars with a magnetic force that beats anything physicists have ever seen.
Not only was it very long, lasting about three seconds, but there were periodic peaks that were remarkably precise, emitting every fraction of a second – like a heartbeat. This is the first time the signal itself is periodic.
The first full-color image from NASA's James Webb Space Telescope has been released. The images are be the deepest and highest resolution ever taken of the universe, according to NASA.
NASA's James Webb Space Telescope has produced the deepest and sharpest infrared image of the distant universe to date. Known as Webb'nas First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail.
Astronauts lose decades' worth of bone mass in space and many do not recover even after a year back on Earth after their missions on the International Space Spation, - a new study finds.
Astronomers have never seen one like this before: a galaxy in miniature, orbiting perilously close to the center of our own galaxy.
Two new worlds of probable rocky mineral goodness have just been found orbiting a star close to our own cosmic neighborhood.
We still don't know just how the first life emerged on Earth. One suggestion is that the building blocks arrived here from space; now, a new study of several carbon-rich meteorites has added weight to this idea.
Compared to most places you might wander in the Solar System, Titan, the giant moon of Saturn, is in many ways strangely familiar to Earth.
Strange double ridges on the surface of Jupiter's ice moon Europa could be signposts to shallow reservoirs of water.
Located in the bright constellation of Centaurus, this luminous cosmic beast is more than 500 times larger than the supermassive black hole at the centre of our own galaxy.
Japanese researchers have discovered more than 20 amino acids on the space rock Ryugu, which is more than 200 million miles (320 million kilometers) from Earth.
Astronomers have discovered two large, mysterious objects blasting out of the brightest black hole in the known Universe.
Scientists have discovered a Super-Earth that is four times the mass of our planet and takes just 10.8 days to complete a whole year.
