Scientists have long sought the particle that carries the force of gravity, but a new theoretical model tosses out that idea entirely – and shows how it could be tested in experiments

Rising concentrations of greenhouse gases decrease the atmosphere's ability to devour space junk, a new study finds.

With wildfires happening more often and burning more area, homes need to be “hardened” to make them more fire-resistant

The Big Wheel, discovered using the James Webb Space Telescope, formed just 2 billion years after the big bang - surprisingly early for a spiral galaxy of a similar size to our Milky Way

The EPA rolls back regulations, NASA launches two exciting missions, and we discuss the surprising way whale urine moves nitrogen across the ocean.

Surveys that ask thousands of people how they spend their time have revealed some surprising activities that seem to make any given day a good one

Researchers examining seismic data recorded on Mars say the have found evidence supporting the presence of liquid water deep inside the Red Planet.

When Betelgeuse goes off, it's going to be the show of a lifetime. But it’s not going to hurt us.

Despite their overall similarities, asteroids are usually pretty distinct from one another. Vesta has a very different spectroscopic profile than Psyche, for example. So it might come as no surprise that another of the main asteroids - Pallas - is in a class all its own except for the 300 or so members of its "family" with similar orbital profiles and spectroscopic lines. A new paper from researchers who were then Visiting Astronomers at NASA's Infrared Telescope Facility (IRTF) in Haiwi'i took a look at members of that family in the infrared for the first time and compared them to a particular Near-Earth object that might have a similar make-up.

Astronomers at the International Astronomical Union report that we have now detected more than 200 gravitational-wave events, most the merger of two black holes.
