Planets

The exoplanet Gliese 12 b is tantalizingly close and moderately warm, situated just 40 light-years away around a red dwarf star. The potentially habitable planet could be a good place to search for alien life, scientists say.

The Juno spacecraft, which orbits Jupiter, has been imaging the giant planet's moon Europa and spotted apparent movement in its icy crust.

The exoplanet WASP-107 b is one of the least dense planets ever discovered. New James Webb telescope observations may reveal how the mysterious world got so 'puffy'.

Previously unpublished photos of Mars' moon Phobos hint that the mysterious satellite may actually be a trapped comet — or perhaps just a piece of one, along with its twin moon Deimos.

An Earth-size planet discovered around a nearby star offers astronomers their first chance for exoplanetary geology.

NASA's Juno spacecraft has spotted the elusive fifth moon of Jupiter transiting the giant planet's Great Red Spot, giving astronomers a rare view of this small but intriguing natural satellite.

Scientists have discovered a bizarre, red-glowing exoplanet named TOI-6713.01, which is loaded with active volcanoes and may be 'melting from within.'

Using the James Webb Space Telescope, scientists have discovered evidence of a carbon-rich atmosphere around the hellish world 55 Cancri e. This marks the best evidence yet of an atmosphere around a rocky exoplanet.

A new water loss mechanism on Venus explains how the planet lost all its water, turning the planet from a potentially habitable world into the parched hellscape we know today.

Newfound rocks on Mars suggest the planet may have once sported an oxygen-rich atmosphere, making it more Earth-like and hospitable to life than previously thought.
