When galaxies merge, we expect them to produce binary black holes (BBHs.) BBHs orbit one another closely, and when they merge, they produce gravitational waves that have been detected by LIGO-Virgo. The upcoming Vera Rubin ...

A pair of astrophysicists at Universidad Nacional Autonoma de Mexico has found, via study of data from the low-Earth orbiting Fermi Gamma-ray Space Telescope, regular gamma radiation pulses emanating from around the black ...
Astrophysicists working with the JWST have found a surprising amount of metal in a galaxy only 350 million years after the Big Bang. How does that fit in with our understanding of the universe?

Astronomers with The LHAASO Collaboration have found that last year's GRB 221009A gamma-ray burst, subsequently nicknamed the Brightest of All Time (BOAT), carried with it 13 teraelectronvolts of energy. In their study, reported ...
While physics tells us that information can neither be created nor destroyed (if information could be created or destroyed, then the entire raison d'etre of physics, that is to predict future events or identify the causes ...

Entropy is one of those fearsomely deep concepts that form the core of entire fields of physics (in this case, thermodynamics) that is unfortunately so mathematical that it's difficult to explain in plain language. But we ...

Black holes are regions in space where the gravitational pull is so strong that nothing can escape them, not even light. These fascinating regions have been the focus of countless studies, yet some of the physics underlying ...
After a distant star's explosive death, an active stellar corpse was the likely source of repeated energetic flares observed over several months—a phenomenon astronomers had never seen before, a Cornell-led team reports ...
