Exploding stars are rare but emit torrents of radiation—one close enough to Earth could threaten life on the planet

Stars like the sun are remarkably constant. They vary in brightness by only 0.1% over years and decades, thanks to the fusion of hydrogen into helium that powers them. This process will keep the sun shining steadily for about ...

Entanglement entropies of nuclear systems found to grow as the volume of those systems

Entanglement is what Einstein called "spooky action at a distance." It is a key part of what distinguishes quantum mechanics from our everyday experience. In quantum mechanics, scientists use a measurement called entanglement ...

AI for astrophysics: Algorithms help chart the origins of heavy elements

The origin of heavy elements in our universe is theorized to be the result of neutron star collisions, which produce conditions hot and dense enough for free neutrons to merge with atomic nuclei and form new elements in a ...
