Exoplanets

The James Webb Space Telescope revealed that the hot Jupiter exoplanet HD 189733 b, located just 64 light-years from Earth, has an atmosphere full of hydrogen sulfide, meaning it likely smells of rotten eggs.

Slovakian artist Martin Vargic's spectacular new infographics artistically portray, visualize and compare more than 1,600 planets in other star systems.

The Gaia space telescope has spotted the dim companions of eight bright stars, suggesting we can expect new glimpses of distant planets.

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 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'.

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

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.

New James Webb Space Telescope observations of the exoplanet WASP-43b reveal that the hot gas giant is tidally locked, meaning one side permanently faces its sun while the other always stares out into space.
