Stars

Scientists have measured for the first time the speed of jets launched by neutron star "vampires" as they feast on victim stars. The breakthrough connects these jets to thermonuclear blasts.

Scientists have discovered that the hottest and brightest stars in the cosmos, blue supergiants, are created when two smaller stars spiral together and merge, new research suggests.

The Hubble Space Telescope has imaged a powerful jet erupting from an envelope of gas and dust that represents a newly born star announcing itself to the cosmos.

The different ways red giants "sing" could affect distance measurements of the universe, potentially helping soothe a cosmic headache: The Hubble tension.

SN 1987A is ringed by a strange string of hydrogen pearls that have puzzled astronomers for a long time, but researchers may finally have an explanation.

Extreme collisions between neutron stars could create exotic particles beyond the standard model, including axions, the hypothetical particle that comprises dark matter.

The Vela supernova remnant looks breathtaking in this image from the powerful DECam, revealing intricacies in debris that resulted from the destruction of a massive star 11,000 years ago.

Betelgeuse appears to be rotating faster than is possible for such a massive star. New research suggests this is an illusion caused by the violently boiling surface of the red supergiant.

Scientists have discovered that some "dead" white dwarf stars hide a metaphorical fountain of youth beneath their skin that helps them delay their cooling processes.

The astrolabe dates from 11th-century Spain and has origins that are Islamic, Jewish and Christian.
