One of these twin stars has likely been snacking on exoplanets
Astronomers have discovered chemical differences between binary stars that indicate one has devoured at least one planet.
NASA X-ray spacecraft discovers supernova wreckage at the heart of the Milky Way
NASA's Chandra X-ray spacecraft has detected the supernova wreckage of a dead star that erupted 1,700 years ago and ejected debris at 2 million miles per hour.
Glittering star cluster image reveals missing patch of stars: ‘We were not looking for the gap, but we found it’
Euclid space telescope observations of ancient globular cluster NGC 6397 reveal a subtle gap in brightness distribution of red dwarf stars.
This star system creates a rare triple eclipse. Here’s what that would look like
A triple star system in which the stars all eclipse one another from our vantage point is standing out as one of the best studied stellar trios.
Scientists locate source of mysterious radio signals after 20 year search: A vampire star and its victim
The origin of enigmatic long-period radio bursts has been shown to be from the clash of magnetic fields as a white dwarf steals matter from a close red dwarf star.
Shockwaves from dying stars may sculpt ‘cosmic wagon wheel’ stellar nurseries, simulations reveal
3D simulations reveal how shockwaves from stellar explosions and winds may carve hub-and-spoke structures in molecular clouds, shaping star formation in the Milky Way.
Red dwarf stars are cosmic killers that eat their own planets
Astronomers have discovered the first evidence that tiny red dwarf stars can devour their own planets.
Scientists just found a supercharged supernova — powered up by a magnetic star corpse
NASA's Fermi Gamma-ray spacecraft has observed a super-bright, supercharged supernova explosion powered up by the creation of a highly magnetic dead star, or magnetar.
Why do some stars become ‘supernova impostors’? Astronomers still don’t quite know
Astronomers call this "eruptive mass loss," and it's a stellar drama we're still trying to fully grasp.
Starbirth shuts down 40,000 light-years from the Milky Way’s core — and astronomers don’t know why
Astronomers have found the boundary of star formation in the Milky Way's spiral disk — and it's not as far out from the center of our galaxy as you might imagine.
