The James Webb Space Telescope has detected water vapor and thick clouds on LTT 9779 b, an ultra-hot Neptune locked in a ...

NASA’s James Webb Telescope captured direct images of gas giants in HR 8799, revealing their carbon dioxide-rich atmospheres.

These gases — composed of carbon, hydrogen, and a halogen, like chlorine — are mostly made by bacteria, algae, fungi, and ...

For decades, astronomers have classified exoplanets into neat categories: rocky Earth-like planets, gas giants like Jupiter, ...

To accomplish these goals, HWO would employ spectroscopy to look for biosignatures in exoplanet atmospheres, as well as direct imaging using a coronagraph. The more ambitious plans for HWO call for a ...

A distant exoplanet discovered, named Enaiposha, is unlike anything found in our own solar system, similar to a "super-Venus" ...

Get Instant Summarized Text (Gist) A Jupiter-like exoplanet, GJ 2126 b, has been detected orbiting an M-dwarf star using the radial velocity method with the HARPS spectrograph. This exoplanet has ...

Astronomers have detected over 5,800 confirmed exoplanets. One extreme class is ultra-hot Jupiters, of particular interest because they can provide a unique window into planetary atmospheric dynamics.

Scientists say they are rethinking how the weather works after creating a 3D map of an exoplanet 900 light-years away and discovering a world with jet streams fueling wild storms. WASP-121b ...

WASP-121 b is the definition of an "extreme" exoplanet — it's so hot that it rains droplets of liquid iron. Now, astronomers have discovered that this planet, located around 900 light-years away ...

Named HD 20794 D, the newly discovered exoplanet orbits a star similar to the Sun, and researchers believe it may be able to sustain liquid water, which is vital for life, as we know it ...
