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...
Current theories predict that low-mass stars should rarely host planets with masses exceeding that of Neptune (17 Earth masses).

LTT 1445Ac, a terrestrial planet in the triple star system LTT 1445, is only 1.07 times the size of Earth, according to a paper to be published in the...
In a paper published in the Proceedings of the Royal Society A: Mathematical Physical and Engineering Sciences, researchers at the University of Cambridge...
TRAPPIST-1 is a nearby system of seven Earth-sized, temperate, rocky exoplanets transiting a Jupiter-sized ultracool red dwarf, ideally suited for in-depth...
HIP 81208 is the first binary stellar system with substellar companions around each stellar component ever found by direct imaging.
Astronomers thought...
Using data from TRAPPIST-South/North, SPECULOOS, and MuSCAT3 facilities, astronomers have discovered an unusual Jupiter-sized exoplanet orbiting the red...
A process called photoevaporation is a potential explanation for several features within exoplanet demographics. Atmospheric escape observed in young Neptune-sized...
The vital role of a carbon molecule called methyl cation (CH3+) in interstellar carbon chemistry was predicted in the 1970s, but the unique capabilities...
Using data from NASA’s Transiting Exoplanet Survey Satellite (TESS) and several ground-based telescopes, astronomers have discovered and validated a...
Observing magnetic star-planet interactions offers promise for determining the magnetic fields of exoplanets. Models of star-planet interactions predict...
The dayside of TRAPPIST-1b, the innermost planet in the seven-planet system TRAPPIST-1, has a temperature of about 227 degrees Celsius (441 degrees Fahrenheit),...
Rocky exoplanets orbiting red dwarf (M-dwarf) stars are among the most promising and abundant astronomical targets for detecting habitable climates. Planets...
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)...
