On Aug. 17, a collision of two neutron stars, the extremely dense corpses of stars more massive than our sun but not quite massive enough to become black holes, collided.

The precursors of heavy elements might arise in the plasma underbellies of swollen stars or in smoldering stellar corpses.

A cataclysmic variable star was found as part of a project using two telescopes from opposite sides of the world.

A microquasar belonging to our Milky Way galaxy has set records by generating cosmic rays with energy levels never before seen.

Caltech simulations reveal what happens when black holes collide with neutron stars—violent cracking, intense shock waves, and short-lived black hole pulsars.

Only a few dozen of these short-lived binaries exist in the galaxy at a time, making the serendipitous find extremely ...

Binary neutron star mergers, cosmic collisions between two very dense stellar remnants made up predominantly of neutrons, have been the topic of numerous astrophysics studies due to their ...

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 ...

"This discovery heralds a broader understanding of the diversity in massive stars' deaths and a need for deeper investigations into the whole landscape of stellar evolution." ...

When white dwarfs—the hot remnants of stars like our sun—are orbited closely by another star, they sometimes steal mass away ...
