It isn’t a secret that humanity and everything around us is made of star stuff. But not all stars create elements equally. Sure, regular stars can create the basic elements: helium, carbon, neon, ...

A teaspoon that weighs a billion tons? Welcome to the world of neutron stars the ultra-dense cores left after colossal ...

Neutron stars—the dense remnants of massive stellar explosions—and their presence in X‐ray binaries serve as natural laboratories for extreme physics. In these systems, matter is transferred from a ...

The collision and merger of two neutron stars—the incredibly dense remnants of collapsed stars—are some of the most energetic events in the universe, producing a variety of signals that can be ...

New simulations tilt the scales for competing theories about excess gamma ray light at the center of the galaxy ...

For decades, astronomers have been vying to identify a source for a mysterious gamma-ray excess at the center of the Milky ...

Astronomers have detected the first “heartbeat” of a newborn star within a cosmic explosion, revealing a rapidly spinning magnetar and reshaping the understanding of gamma-ray bursts.

"What is remarkable is that the time between pulse pairs seems to follow a choreographed pattern." Using the world's most advanced radio telescopes, astronomers have discovered a spinning dead star so ...

New simulations of neutron star mergers reveal that the mixing and changing of tiny particles called neutrinos impacts how the merger unfolds, including the composition and structure of the merger ...
