Astronomers thought...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have discovered carbon dioxide and methane in the atmosphere of the habitable zone exoplanet...
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...
Venus and Earth provide astonishingly different views of the evolution of a rocky planet, raising the question of why these two rocky worlds evolved so...
White dwarf pulsars include a rapidly spinning, burnt-out stellar remnant called a white dwarf, which lashes a companion red dwarf with powerful beams...
A team of U.S. astronomers has discovered that two-thirds of the planets around M dwarfs (red dwarf stars) could be roasted by extreme tidal forces, sterilizing...
Using data from NASA’s Transiting Exoplanet Survey Satellite (TESS) and several ground-based telescopes, astronomers have discovered and validated a...
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...
Using spectral data from Webb’s Near-Infrared Spectrograph (NIRSpec), astronomers determined that the warm super-Earth Gliese 486b either has a water-rich...
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)...
