Researchers in the U.S., Canada and China independently concluded that the intense radio pulses could be from magnetars -- dead stars within the Milky Way.

When faraway stars explode, they send out flashes of energy called gamma-ray bursts that are bright enough that telescopes back on Earth can detect them. Studying these pulses, which can also come ...

Red dwarf stars are known for sudden, intense bursts of life-killing radiation, and can vary in brightness by as much as 50 percent when they're in the mood.

Except now it's very small, only about the size of a city, and around 1 million times more dense than the Earth. This stellar zombie is known as a neutron star.

PASADENA, Calif.—Galaxies have been experiencing vigorous bursts of star formation from much earlier in cosmic history than previously thought, according to new observations by a Caltech-led ...

Astronomers have been trying to detect atmospheres on planets orbiting TRAPPIST-1, but bursts of radiation from the star make this challenging ...

Neutron stars themselves are the remnants of massive stars that exploded in supernovae and then collapsed, packing an immense amount of matter into a small, dense core.

And the stars were truly giants, with KSN 2011a having a radius of about 280 times that of the Sun and KSN 2011d having one that's nearly 500 times the radius of our Sun.
