How do magnetars get so magnetic? A study of stellar explosions shows that the long-accepted theory might be wrong.

The KATRIN experiment is closing in on the mass of the neutrino, which could point to new laws of particle physics and shape theories of cosmology.

Playing with a simple bean machine illustrates how deterministic laws can produce probabilistic, random-seeming behavior.

John Goodenough, M. Stanley Whittingham and Akira Yoshino shared the 2019 Nobel Prize in Chemistry for developing lithium-ion batteries, "the hidden workhorses of the mobile era."

The astronomers Michel Mayor and Didier Queloz won half of the prize for their 1995 discovery of a Jupiter-like planet orbiting a nearby star. The cosmologist James Peebles won the other half for work exploring the structure of the universe.

After successfully predicting laboratory earthquakes, a team of geophysicists has applied a machine learning algorithm to quakes in the Pacific Northwest.

A giant star’s death throes may offer the first evidence of a pair-instability supernova, and a glimpse of the first stars in the universe.

A new measurement appears to have eliminated an anomaly that had captivated physicists for nearly a decade.

There are many different ways to think about probability. Quantum mechanics embodies them all.
