Scientists have long overlooked white dwarfs as hosts for habitable exoplanets, assuming their lack of fusion would make life ...

White dwarf stars could host habitable planets. Fast planetary rotation reduces cloud cover, keeping surface temperatures stable.

Last year, astronomers discovered an unusual Earth-size exoplanet they believe has a hemisphere of molten lava, with its ...

Planet demographics reveal a puzzling lack of worlds in a certain size range throughout the galaxy F or centuries our solar system was the only planetary system known to humans. We had no proof other ...

An international team has confirmed the discovery of a super-Earth in the habitable zone of a Sun-like star. This planet, named HD 20794 d, could offer conditions conducive to life. Located ...

Astronomers used a 3D global computer model to compare the climates of exoplanets in different stellar and orbital configurations. They found that a planet orbiting a white dwarf star would offer a ...

An international team of scientists has confirmed the discovery of a super-Earth—a planet larger than Earth but smaller than ...

Astronomers have detected an exoplanet just twenty light years away that's residing in its star's habitable zone.

A new study examines how much material from the closest star system to Earth will end up in orbit around the Sun, and how ...

The Chandra X-ray telescope and other observatories are being used to study stars that could potentially harbor habitable planets. Future observatories will use the data to narrow down the list for ...
