A nearby star system, teetering on the edge of a spectacular explosion, promises a rare cosmic show that’ll be visible to the naked eye.
The brightest gamma-ray burst of all time came from a supernova but mysteriously didn't show signs of heavy elements.
These fast-moving outbursts of material are slightly different from those launched by black holes.
The super-dense object doesn't quite fit with what we know about black holes or neutron stars.
Astronomers are trying to figure out how an isolated brown dwarf could produce such a phenomenon.
In a rare cosmic event, an asteroid will eclipse Betelgeuse on December 11, causing a brief but significant disappearance of this bright, red star.
Located one billion light-years away, the star—thought dead—appears to be going through a revival, with scientists spotting energetic flares.
Vela is nearly 1,000 light-years from Earth and is spewing astonishingly energetic gamma-rays into space.
The spinning, dead star was emitting radiation in two modes, and a team of scientists believes it knows why.
The object has a surface temperature 38% hotter than our host star.
An apparent magnetized neutron star is exhibiting a remarkably long period, emitting radio waves once every 22 minutes.
The burnt-out star has one side composed of hydrogen and the other composed of helium. Astronomers have never seen anything like it.
An international team of astronomers has discovered a late-stage star that harbors a planet it should have devoured.
Astronomers argue that a recent study forecasting a relatively imminent stellar explosion misses the mark.
The exploded star is 25 million light-years away in the Pinwheel Galaxy.
The observations are a first for astronomy. Let's hope our Sun doesn't get any ideas.
The astounding outburst came from a galaxy 2 billion light-years away. It's the "BOAT"—the brightest of all time.
The white dwarf is the dead core of a star that burned out a billion years ago.
The binary system will end in a massive, gold-forming explosion.
These 'ultracool' stars have such low temperatures that they only emit infrared light.
