Astronomers have discovered a relatively cool and small exoplanet orbiting a nearby star, with a “year” of several months. The find offers a rare opportunity to study planets and solar systems like ...

A new gas giant world discovered by citizen scientists using data from NASA's exoplanet-hunting spacecraft TESS is cool, literally and figuratively. This makes TOI-4465 b a rare case of a giant planet ...

Artist's view of exoplanet SPECULOOS-3 b orbiting its star. The planet is as big as the Earth, while its star is slightly larger than Jupiter, but much more massive. (NASA/JPL-Caltech via Courthouse ...

Learn about HD 137010 b, a cold Earth‑sized planet candidate that sits near the outer edge of its star’s habitable zone.

Exomoons represent a crucial missing puzzle piece in our efforts to understand extrasolar planetary systems. To address this deficiency, we here describe an exomoon survey of 70 cool, giant transiting ...

Astronomers observing exoplanet GJ 3470 b saw evidence of water, carbon dioxide, methane and sulfur dioxide. Astronomers hope the discovery of this exoplanet's sulfurous atmosphere will advance our ...

We have a couple of techniques that allow us to infer the presence of an exoplanet based on its effects on the light coming from its host star. But there’s an alternative approach that sometimes works ...

Exoplanet science has entered an exciting new phase with the development of the EXCITE mission, a groundbreaking project designed to enhance our understanding of exoplanet atmospheres. Unlike ...

NASA has announced the discovery of an Earth-like planet orbiting a Sun-like star that shares several other similarities with ...

A new Earth-sized planet, SPECULOOS-3 b, was discovered orbiting a cool red dwarf star. The planet is very close to its star, resulting in a 17-hour orbital period. High radiation levels likely mean ...

A new study expands the search for life beyond our solar system by indicating that 17 exoplanets (worlds outside our solar system) could have oceans of liquid water, an essential ingredient for life, ...

The sulfur-laden atmosphere discovered on gaseous exoplanet GJ 3470 b, show here in an illustration orbiting its star in the constellation Cancer, could help researchers figure out how it (and similar ...
