New measurements by NASA’s New Horizons spacecraft show higher than model-predicted levels of interstellar dust as the spacecraft approaches the putative outer edge of the Kuiper Belt.
The quasar – named J0529-4351 – is both the most luminous object known to date and the fastest-growing black hole currently known.
Does life appear independently on different planets in the galaxy? Or does it spread from world to world? Or does it do both? New research shows how life could spread via a basic, simple pathway: cosmic dust.
For a quiet, dusty lump of a planet we see today, Mars has had a surprisingly violent history, one that could reveal some clues about Earth.
NASA, the main sponsor with experiments on board, hopes to jumpstart lunar economy ahead of astronaut missions.
Scientists identified water on two main-belt asteroids, 7 Iris and 20 Massalia, using data from the now-defunct SOFIA airborne observatory.
Scientists have discovered that a pair of rings circling an asteroid-like chunk of rock in the cold reaches of space out past Jupiter are likely being shepherded by a tiny, unseen moonlet.
By analyzing the images obtained with Pan-STARRS, astronomers have serendipitously discovered a new protoplanetary disk located some 800 light years away.
On new recently released NASA images show the moons of Saturn in all their glory, as if they came straight out of the pages of science fiction.
NASA scientists are just getting started in their analysis of fragments brought back from the Bennu asteroid, and the early indications are that the material it contains originated from an ancient ocean world.
Early analysis of the fragments has shown something equally rare. The meteorite is an aubrite, a class with unknown origins that some scientists argue may be pieces of the planet Mercury.
The moon has shrunk by more than 45 metres in circumference over the last few hundred million years because of its core gradually cooling.
The beginning of the Universe has always been something of a chicken-and-egg problem. Did stars and galaxies form first, with black holes slowly coalescing in their midst? Or did black holes appear before the first galaxies?
Saturn's small, crater-covered moon Mimas may have a vast ocean under its thick icy surface, according to a new paper.
On February 3, 2024, NASA’s Juno spacecraft made a second close flyby of Io, the third largest of Jupiter’s moons. We were able to see a volcunic erruption there like never before.
