The fastest-spinning white dwarf ever discovered is a shrinking cosmic vampire feasting on a stellar companion. A feeding process is pushing the dead star toward an imminent supernova explosion.

Astronomers have found the fastest spinning star ever discovered. The hot blue giant rotates at a dizzying 1 million mph (1.6 million km/h), or 100 times faster than our Sun. The star is close to the ...

New ultraviolet observations indicate a Milky Way star is spinning nearly 200 times faster than Earth’s sun, the probable result of a merger between two sun-like stars whose binary orbit recently ...

(Santa Barbara, Calif.) –– An international team of scientists has found the fastest-rotating massive star ever recorded. The star spins around its axis at the speed of 600 kilometers per second at ...

Strong darkening observed around the equator of Vega suggests that the fifth brightest star in Earth’s sky has a huge temperature difference of 4,000 degrees Fahrenheit from its cool equatorial region ...

Astronomers have discovered a strange spinning star that appears to be older than the explosion that gave birth to it, scientists say. The star is a pulsar, a rotating, super-dense core left behind ...

Vega is a fundamental reference star for astronomers. But it seems that our perceptions of it have been misconceived — rather than spinning slowly, the star is a rapid rotator seen pole-on. For ...

Astronomers have discovered the flattest star yet, with a radius at least 50% larger at its equator than at its poles. Armando Domiciano de Souza of the University Laboratory of Astrophysics in Nice ...
