Exoplanets

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.

Using the NASA exoplanet-hunting spacecraft TESS, astronomers have discovered a hot Jupiter dancing with a hidden super-Earth companion.

Young, hot planets could soak up a lot of water into their core, with up to 10 times more water inside than on the surface of the planet.
