The planetary system with a white dwarf, an Earth-like planet and a brown dwarf cannot be seen; the point of light in (c) is from the background source star that is no longer magnified. view more .

Astronomers have found two giant planet candidates orbiting two white dwarfs. More proof that giant planets can surve their stars' red giant phases. Credit: Madden/Cornell University.

The Planet’s Survival and the White Dwarf’s Violent Past. This Earth-like planet, with a mass approximately 1.9 times that of Earth, is orbiting its white dwarf star at a distance of 2.1 ...

Scientists have shown that extraterrestrial life on alien planets orbiting white dwarfs stars could be detectable, under certain circumstances, by the upcoming James Webb Telescope.

It has been noted that white dwarfs (WDs) have long-lived habitable zones and that a large fraction of WDs may host planets. We point out that during a transit of an Earth-mass planet across a WD, the ...

Astronomers using the Kepler space observatory have spotted a planet circling around WD 1145+017, a white dwarf 570 light years away. Not that it's in great shape, mind you.

But somehow, this particular planet survived, even though it is close enough to the white dwarf that it completes an orbit in just 34 hours. That’s 60 times faster than Mercury orbits the sun.

Gaensicke and his colleagues studied a white dwarf called WDJ0914+1914, which lies about 2,040 light-years from Earth. In data gathered by the Sloan Digital Sky Survey, the researchers detected ...

His findings, published in The Astrophysical Journal Letters, suggest that for a typical white dwarf with a mass of 0.6 times that of the Sun, an Earth-like planet located at approximately 0.012 ...

The giant planet is orbiting the white dwarf just outside the gas disc. The blast of high-energy photons that it receives from the white dwarfs evaporates its atmosphere, which is mainly composed ...

When planets and moons orbit a white dwarf, the star's gravity may rip them apart into tiny pieces, which may happen in Earth's far future.
