In about 7 billion years our sun will become a white dwarf, the name for a star that depleted its nuclear fuel and only shines as a remnant of what it once was. No star is ever born as a white dwarf ...

The Hubble Space Telescope has been used to determine the mass of white dwarf star LAWD 37. It is "56 percent the mass of our ...

For the first time, astronomers have discovered evidence for a giant planet orbiting a tiny, dead white dwarf star. And, surprisingly, the Neptune-sized planet is more than four times the diameter of ...

Astronomers have traced the origin of a colossal white dwarf to a catastrophic crash between two dead stars, turning a quiet ...

Astronomers have discovered the smallest but most massive white dwarf ever found. The tiny star is only the size of our Moon, but packs in more mass than the Sun, meaning it’s approaching the ...

Astronomers have discovered the smallest yet most massive white dwarf star ever seen. According to a new study published Thursday in the journal Nature, the "very special" star has a mass greater than ...

Only a smidge bigger than the moon, a newfound white dwarf is the smallest of its kind known. The white dwarf, a type of remnant left behind when certain stars peter out, has a radius of about 2,100 ...

White dwarfs, the compact remnants of low- to intermediate-mass stars, offer a unique window into the fate of planetary systems. Recent observational and theoretical work has revealed that many white ...

The identification of J1912-4410 marks only the second discovery of a white dwarf pulsar, a rare type of celestial object emitting pulsed radiation. This system features a rapidly rotating white dwarf ...

In general, it's very difficult to have a star transform into a white dwarf and wind up with a planet very close in orbit around it without that planet being destroyed by a tidal disruption event. A ...

March 2 (UPI) --An unusual white dwarf star was formed by a merger between two smaller white dwarfs, according to a new analysis by an international team of astronomers. The ultra-massive white dwarf, ...
