In June, scientists presented compelling evidence that they discovered a massive "hum" of low-frequency gravitational waves rippling through the universe. Similar to the ripple effect that occurs when ...

About a year ago, astronomers excitedly reported the first detection of electromagnetic waves, or light, from a gravitational wave source. Now, a year later, researchers are announcing the existence ...

So far, astrophysicists have only detected gravitational waves from binary systems — the mergers of either two black holes, two neutron stars or one of each. Although astrophysicists theoretically ...

Black holes crashing together may be revealing clues about dark matter hidden across the universe. Physicists created a new ...

It now takes just a fraction of a minute to detect neutron star mergers, thanks to advancements in a machine-learning-driven approach to astronomy. Reading time 3 minutes A team of researchers just ...

After the death of a massive, spinning star, a disk of material forms around the central black hole. As the material cools and falls into the black hole, new research suggests that detectable ...

A new study published in Physical Review Letters explores the possibility that a strongly supercooled, first-order phase transition in the early universe could explain gravitational wave signals ...

Chinese researchers are poring over a puzzling gravitational wave signal that appears to defy the standard script of black hole collisions, reviving one of physics’ most audacious possibilities: that ...

There may be an ultraheavy explanation for the mystery surrounding the origins of the highest-energy particles ever observed. Ultrahigh-energy cosmic rays are particles from space that strike Earth ...

A new study, published in the journal Physical Review Letters, suggests that some of the highest-energy cosmic rays could ...
