Astronomers in China have observed a pulsar that becomes partially eclipsed by an orbiting companion star every few hours.

The future of yellow dwarf stars, like our sun, is determined almost entirely by their mass. The most massive stars, about ...

Astronomers have uncovered a bizarre star, ASKAP J1832, that pulses radio waves and X-rays every 44 minutes—thousands of times slower than typical pulsars. This rare object also dims dramatically over ...

A new simulation by researchers shows how a neutron star violently cracks seconds before vanishing into a black hole.

A neutron star's final moments may spark violent starquakes, monster shock waves, and even a fleeting, never-before-seen ...

The stars in a binary can vary widely in mass, size, and brightness, and their interactions often shape their evolution in dramatic ways. In some cases, the gravity from one star can drag material ...

A U.K.-based aerospace company will soon establish its U.S. headquarters in the Austin area. Maddow Blog | ‘No Kings’ ...

Astronomers have discovered a "teenage vampire" dead star in the process of devouring a companion star during a short-lived, "missing link" phase of its evolution.

A team of astrophysicists, led by Elias Most from Caltech, has modeled the milliseconds preceding the destruction of a neutron star by a black hole. Their work, published in The Astrophysical ...

The newly identified pulsar orbits a companion star every 3.6 hours and is eclipsed by its companion for approximately one-sixth of each orbit — a phenomenon similar to solar or lunar eclipses ...

“ASKAP J1832–0911 is currently the only LPT detected with (pulsed) X-ray emission — perhaps unsurprisingly, given its extreme ...

Astronomers have spotted a star acting unlike any other ever observed as it unleashes a curious combination of radio waves and X-rays, pegging it as an exotic member of a class of celestial objects ...
