It's called TOI-1452b, and measurements of its size and mass suggest a density profile consistent with a global liquid ocean. An exoplanet is just 100 light-years from Earth
Australian astronomers have discovered one of the biggest black hole jets in the sky. Spanning more than a million light years from end to end, the jet shoots away from a black hole with enormous energy, and at almost the speed of light.
An international team of researchers studying dust samples retrieved by the Hayabusa-2 space probe, has found that some of its dust grains are older than the solar system.
The aftermath of an epic collision involving at least one neutron star has been captured for the first time in the millimeter range of radio frequency wavelengths.
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.
