This wasn't what anyone was hoping for.
Physicists think this might be the first of many hidden states of matter that could be uncovered using laser flashes.
Mathematicians have uncovered a big new piece of evidence for one of the most famous unproven ideas in mathematics, known as the twin prime conjecture.
If you'd looked up into the sky in Kyoto, Japan, on April 28, 2017, you may have seen a preview of an event that could, far down the road, threaten the whole Earth.
When 'Oumuamua passed through our solar system in 2017, no one could figure out where the object came from. But astronomers think they've worked out how Comet 2I/Borisov got here.
SpaceX has never flown a person into space in its first spacecraft, the Crew Dragon. But already Musk is showing off his big, shiny Starship — and NASA is bristling.
The new experiment demonstrated a bizarre quantum effect from the double-slit experiment at an unprecedented scale.
Astronomers have long hunted a mysterious planet in the outer reaches of our solar system. These scientists think that it might really be a primordial black hole,
The KATRIN experiment has turned up a new, more-precise-than-ever measurement for the barely-detectable neutrino mass.
Often, when we don't have an immediate explanation for something strange in space, some people blame aliens. But better explanations usually come along in time.
A new, hours-long Hubble study of the collision site revealed never-before-seen details of the neutron-star merger
Astronomers have detected a neutron star system blasting X-ray light at Earth and detected a rare, months-long pattern in those light bursts.
Hurricane Dorian has strengthened to a Category 3 storm as of 2 p.m. Eastern on Friday (Aug. 3), and is expected to reach Florida Monday.
Mars mission managers are dealing with the biggest source of electromagnetic interference in the solar system.
Three giant gamma-ray flares have been detected in the last 40 years. A new paper on magnetars cracking themselves open could explain why.
A new paper uses data about the structure of the entire universe to measure the mass of one of its smallest, hardest-to-study components.
There's a galaxy not too far from our own that astronomers were very sure was shaped like an X, but a new, clearer radio telescope image shows that the galaxy is more like a stretched-out blob.
It's time to find all the missing black holes. That's the argument advanced by a pair of Japanese astrophysicists who want to find "isolated black holes."
