New telescope technologies, including space-based tools such as the James Webb Telescope, have enabled us to discover thousands of potentially habitable exoplanets ... NASA’s OSIRIS-REx mission ...

Understanding exoplanet evolution could help solve the mystery of the 'hot Neptune desert.' As astronomers delve deeper into the diversity of worlds orbiting distant stars, a new study suggests ...

"I do not believe we yet have convincing evidence of the presence of DMS in K2-18b's atmosphere." In 2023, debate erupted in the astronomy community about whether life could exist on an exoplanet ...

A selection of exoplanets that orbit in the habitable zone around their stars — where water can sit in liquid form on the surface. From left: Kepler-22b, Kepler-69c, Kepler-452b, Kepler-62f ...

Astronomers have discovered two exoplanets around TOI-1453, a star about 250 light years away. These two exoplanets, a super-Earth and a sub-Neptune, are common in the galaxy, yet are absent from ...

The frequency of that stellar wobble reveals an exoplanet’s orbital period and distance from its star, and its strength provides an estimate of the unseen world’s mass. The observations ...

An artist’s rendering of Barnard’s Star, as seen from one of the newly discovered exoplanets orbiting it International Gemini Observatory / NOIRLab / NSF / AURA / P. Marenfeld under CC BY 4.0 ...

Normally, the Webb telescope only detects exoplanets by glimpsing them when they cross in front of their host star. This "transiting method" was how Webb indirectly detected CO2 in the atmosphere ...

Using data from NASA's Transiting Exoplanet Survey Satellite (TESS) and the HARPS-N high-resolution spectrograph, the researchers were able to identify TOI-1453 b and TOI-1453 c, the two ...

In 2022, the Webb telescope detected unequivocal evidence of carbon dioxide in the atmosphere of a distant exoplanet called WASP-39b. But that detection was made indirectly, so the latest ...
