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 .

A gas giant planet was recently discovered orbiting a white dwarf star, providing a glimpse at what our own solar system could look like after the sun expands into a red giant and destroys most of ...

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.

Astronomers spotted a potential Earth-size rocky world orbiting a white dwarf, suggesting a future in which our planet outlives its star. By Jonathan O’Callaghan In six billion years the sun ...

They could be very distant red background galaxies, but given how many are seen in the images, the chance of two of them being so apparently close to the white dwarfs is low.

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 ...

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.

A 2020 microlensing event was caused by a planetary system with an Earth-like planet and brown dwarf. The star type was uncertain. The team has determined that the star is a white dwarf, a system ...
