Exoplanets

A new study suggests that stars may chomp on planets way more often than you'd expect.

WASP-12b, an ultrahot Jupiter planet molded into the shape of an egg, is set to nose-dive into its star.

The discovery of the first exoplanets was a watershed moment for both science and science fiction, which has attempted to keep pace with scientific knowledge of other worlds.

Incredible images captured by the Very Large Telescope in Chile reveal unique insights into planet formation around young stars.

"I would imagine that all Trappist-1 planets are going to have a hard time holding on to any atmosphere."

Our universe's lack of super-Earths or mini-Neptunes could be caused by some planets migrating toward the hearts of their systems early on in their lives.

A young star's extreme outburst could show us the violent conditions that may be experienced by planets, including those of the solar system, as they form in infant systems.

Infant exoplanets may not be spherical as astronomers have always assumed. Instead, they may be oblate spheroids, like the 'Smarties' candy found in Europe.

Do the Milky Way's most common planets, mini-Neptunes, have atmospheres filled with opaque clouds or a more transparent haze?

NASA's exoplanet-hunting spacecraft TESS has spotted a 'super-Earth' in the habitable zone of its red dwarf star, with indications it may have Earth-sized company.
