Planets

Potentially hazardous asteroids pose a risk to Mars missions, but they can also yield insight into the history of the Red Planet and the early solar system, new research suggests.

Japan has lost contact with its Akatsuki probe, the only spacecraft currently in orbit around Venus.

New research shows that a planet spotted around the real-life star 40 Eridani A, famous for hosting Dr. Spock's fictional home world in 'Star Trek', may have been an optical illusion all along.

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Previously unpublished photos of Mars' moon Phobos hint that the mysterious satellite may actually be a trapped comet — or perhaps just a piece of one, along with its twin moon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