A new study modeled the chemistry of TOI-270 d, an exoplanet between Earth and Neptune in size, finding evidence that it could be a giant rocky planet shrouded in a thick, hot atmosphere. TOI-270 d is ...
A strange “forbidden” planet spotted by the James Webb Space Telescope is turning planetary science on its head. TOI-5205 b, a Jupiter-sized world orbiting a small, cool star, has an atmosphere ...
The search for Earth 2.0 has begun in earnest. But there's a huge variety of exoplanets out there, so narrowing down the search to focus valuable telescope time on only the best candidates is critical ...
(CNN) — Astronomers have found an Earth-size planet that isn’t like Earth at all. Instead, the exoplanet, called LP 791-18 d, is likely covered in volcanoes and may experience eruptions with the same ...
A nearby Earth-sized planet offers a rare chance to study how atmospheres survive or disappear on rocky worlds.
Astronomers might be close to confirming the presence of an Earth-like atmosphere on an exoplanet for the first time, if more detailed analyses verify preliminary observations from the James Webb ...
The Webb telescope has detected a dark, atmosphere-less rocky exoplanet that could shed light on how Earth-like worlds die.

Scientists used AI to comb through NASA’s TESS data and confirmed 100 hidden exoplanets — including worlds that orbit their star in under a day
A machine-learning system built to hunt for overlooked planets has pulled 118 new worlds out of NASA’s existing telescope data, including a handful that complete a full orbit around their star in less ...

NASA exoplanet-hunting spacecraft and citizen scientists discover a cool new alien world
A new gas giant world discovered by citizen scientists using data from NASA's exoplanet-hunting spacecraft TESS is cool, literally and figuratively. The extrasolar planet, or "exoplanet," designated ...
In a zesty new discovery, scientists have unearthed a strange lemon-shaped exoplanet. It is unlike one we have seen before, challenging many of the previously held assumptions about planetary ...
