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."
There are voids in the universe, and we can't see them properly. But the good news is that astronomers just got much better at not seeing them properly.
There are turbulent electrical currents coursing through the gas giant's outer atmosphere, producing brilliant auroras.
Trump administration officials are removing references to climate change from U.S. Geological Survey (USGS) press releases, according to a ClimateWire report.
A team of researchers have posted a paper in which they claim to have achieved a holy grail of materials science: creating metallic hydrogen in a laboratory.
Something dark is spreading across the surface of Titan, and we may finally have some idea what it is.
A NASA mission to an ancient iron-nickel hunk has entered its final design phase, a key milestone on the way to reaching the distant destination in the mid-2020s.
There's something flashing us on the moon, and we don't know what it is. But that might be about to change.
SpaceX put 60 bright satellites in space May 23, and astronomers are sounding the alarm about the eventual 12,000-strong Starlink constellation SpaceX plans.
A new paper could end up being a big step toward solving one of the oldest unanswered puzzles in mathematics: Is the Riemann hypothesis correct?
There's a binary star system out there in the Milky Way, and it's followed a very simple pattern since the 1890s. Now, it's breaking its old habits.
Jupiter's magnetic field has changed since the 1970s, and now physicists think they know why it's happening.
The biggest, most expensive science experiment in the world might be losing all its dark matter. But physicists are looking on the bright side.
