Exoplanets

A sodium cloud detected in the vicinity of an exoplanet named WASP-49 b hints at the presence of a natural satellite, also known as an exomoon.

Using the James Webb Space Telescope, astronomers have found a "first of its kind" world, an exoplanet that is twice the size of Earth and has an atmosphere packed with steam.

Astronomers have discovered a low-mass "sub-Earth" planet orbiting the closest solo star to the solar system, Barnard's star, that has a year lasting just three Earth days.

A newly discovered Earth-size world orbiting a dead white dwarf star gives scientists a hint of what the solar system may look like in billions of years.

Yet another faraway world has come to sharper focus thanks to the collective scientific muscle of citizen scientists.

Using the James Webb Space Telescope astronomers have found that a strange inflated exoplanet is even weirder than they realized finding a strange asymmetry in its atmosphere.

Astronomers have discovered a hidden feature in exoplanet distribution that could explain the absence of so-called "hot-Neptunes" close to their stars.

"Iron Winds and Metal Rain." Not the title of a heavy metal album but an accurate weather prediction for a hellish exoplanet called WASP-76b.

A network of citizen scientists recently found a "warm" Jupiter 300 light-years from Earth that can reveal clues about how our own Jupiter and solar system evolved.

The complex history of the orbits of the TRAPPIST-1 planets has been revealed, showing how they interacted with the disk of gas and dust that gave birth to them.
