Stars

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.

Euclid space telescope observations of ancient globular cluster NGC 6397 reveal a subtle gap in brightness distribution of red dwarf stars.

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.

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.

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.

Astronomers have discovered the first evidence that tiny red dwarf stars can devour their own planets.

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.

Astronomers call this "eruptive mass loss," and it's a stellar drama we're still trying to fully grasp.

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.

"These measurements vastly expand our understanding of how stellar neighborhoods like our own are built."
