Neutron stars explained through stellar remnants and collapsed stars, revealing extreme density, gravity, magnetism, and ...

Describing matter under extreme conditions, such as those found inside neutron stars, remains an unsolved problem. The ...

A distant neutron star has abruptly erupted in brightness, surging to roughly one hundred times its usual output and leaving astronomers scrambling to explain what could drive such a violent change.

Scientists from several institutions, including the University of Chicago, discovered a lemon-shaped planet with an ...

A double blast of dying stars may be the first observed case of a long-hypothesized, never proven “superkilonova.” Although ...

Columbia Professor Brian Metzger helped other astronomers interpret their observations of the unexpected stellar event.

A puzzling cosmic blast detected in both light and gravitational waves may hint at a previously unseen type of explosion, challenging astronomers to rethink how neutron stars are born and collide.

When the most massive stars reach the ends of their lives, they blow up in spectacular supernova explosions, which seed the ...

Astronomers may have discovered the first example of an explosive cosmic event called a "superkilonova," in the form of a gravitational wave signal detected on Aug. 18, 2025.

A research team led by Caltech may have just discovered the first-ever superkilonova, a cosmic phenomenon in which a star ...

A double explosion, in which a dying star split, then recombined, may be a long-hypothesized but never-before-seen "superkilonova." ...
