A protective atmosphere, a friendly Sun, and lots of liquid water — Earth is a special place. Using the unprecedented capabilities of the NASA/ESA/CSA...
Ultracool dwarf stars are widespread in the solar neighborhood. Nevertheless, their extremely low brightness has left their planetary population largely...
Using data from NASA’s Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered and characterized a habitable zone planet orbiting the...
The newly-discovered planet has a radius of 1.03 Earth radii and a temperature between 27 and 127 degrees Celsius (81-261 degrees Fahrenheit), with the...
Wolf 1069b is the sixth closest Earth-mass exoplanet situated in the conservative habitable zone of its parent star, after Proxima Centauri b, Gliese 1061d,...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have validated the discovery of a warm, 0.99 Earth-radius exoplanet interior to the habitable...
The newly-discovered alien world, named TOI-700e, is 95% Earth’s size and likely rocky.
An artist’s impression of TOI-700e (larger planet) and TOI-700d....
The two temperate Earth-mass planets are located within the habitably zone of Gliese 1002, a red dwarf star that lies just 4.84 parsecs (16 light-years)...
Nitrous oxide (also known as laughing gas) — a product of microbial nitrogen metabolism — is a compelling exoplanet biosignature gas with distinctive...
Astronomers using data from NASA’s Kepler Space Telescope have discovered an Earth-sized planet in the habitable zone of a low-mass star called Kepler-1649.
An...
Using NASA’s Transiting Exoplanet Survey Satellite, the agency’s Spitzer Space Telescope and other facilities, astronomers have discovered a compact...
The Habitable Exoplanet Observatory (HabEx) would use a telescope with a mirror larger than Hubble’s, and would employ origami techniques to utilize...
Astronomers using the CARMENES (Calar Alto high-Resolution search for M dwarfs with Exoearths with Near-infrared and optical Échelle Spectrographs) instrument...
Understanding which chemical elements are present in a star in what abundances can help astronomers estimate the makeup of planets that orbit them, which...
A rocky exoplanet roughly the same size as Earth has been discovered orbiting a nearby low-mass star, thanks to new data gathered by ESO’s High Accuracy...
