The massive planet LHS 3154b orbits a star much smaller than Earth's sun, and its discovery could upend everything we think we know about how solar systems form.
Six exoplanets with sizes between Earth and Neptune have been in rhythm with each other since they were born around the same star 4 billion years ago, new research suggests.
New research finds that certain large exoplanets are shrinking due to internal processes, creating an abundance of rocky 'super-Earths'.
Clouds of silicate sand exist high in exoplanet WASP-107b's atmosphere, new James Webb Space Telescope observations reveal.
Several exoplanets at the edge of our galaxy could have formed continents — and advanced life — 5 billion years earlier than Earth, new research suggests.
The exoplanet WASP-17b's atmosphere is full of quartz clouds, according to a new James Webb Space Telescope observations.
The hellish super-Earth '55 Cancri e' may be constantly losing and re-growing its atmosphere, a new study of the planet's strange transit signals suggests.
NASA's James Webb Space Telescope has detected potential traces of dimethyl sulfide, a chemical only known to be created by phytoplankton on Earth, in the atmosphere of an exoplanet believed to have its own liquid ocean.
Researchers have shown that if the James Webb Space Telescope was pointed at Earth from a distant star, it could detect the signatures of intelligent life in our planet's atmosphere.
