Exoplanets

"The planet is basically super fluffy."

Astronomers have discovered an Earth-size planet orbiting a red dwarf star, making just the second planetary system seen around one of these tiny, cool, dim, but common, stars.

Described as being like "Io on steroids," a newly discovered exoplanet is the victim of a tug of war between its neighboring planets and its star.

55 Cancri e is a super-Earth planet that appears composed of diamond-like carbon — now, thanks to the JWST, astronomers have found the world has "grown" a second atmosphere.

Citizen scientists have spotted a truly remarkable planet in a binary system's habitable zone. They gave a Harry Potter-inspired nickname.

WASP-12b is a planet on a date with a fiery destiny, doomed to plunge into its sun-like star. Scientists may finally know why some hot Jupiters eventually death spiral into their stars.

The JWST has performed a weather report for a distant hot Jupiter exoplanet, finding winds three times as fast as a jet fighter, clouds made of rock and temperatures hot enough to melt lead.

NASA's exoplanet hunter TESS may have detected its first free-floating planet with a little help from Einstein.

Scientists may have discovered how JuMBOs, strangle binary objects found in Orion, may have gone rogue while staying gravitationally bound. The discovery may shake up theories of planet formation.

The CHEOPS mission has seen tantalizing hints of the rainbow-like glory effect over WASP-76b, an extreme world where iron rains heavily on one side of the planet.
