In a new study, a team of astronomers from Penn State and NASA’s Jet Propulsion Laboratory analyzed when and where human deep space transmissions would...
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...
This planet candidate, Alpha Centauri Ab, could be a gas giant, orbiting 1 to 2 times the distance between Sun and Earth, according to two papers to be...
Lava planets are rocky exoplanets that orbit so close to their host star that their dayside is hot enough to melt silicate rock.
Boukaré et al. introduce...
Radiolysis induced by Galactic cosmic rays could provide a viable energy source for microbial metabolism in the subsurface environments of rocky planetary...
Named L 98-59f, this planet is a non-transiting super-Earth with a minimal mass of 2.8 Earth masses on a 23-day orbit inside the habitable zone of the...
Using the Enhanced Resolution Imager and Spectrograph (ERIS) instrument on ESO’s Very Large Telescope (VLT), two teams of astronomers have detected a...
The radius of a planet is a fundamental parameter that probes its composition and habitability. Precise radius measurements are typically derived from...
The hot-Jupiter exoplanet HIP 67522b orbits its parent star, HIP 67522, so tightly that it appears to cause frequent flares from the star’s surface,...
Astronomers have used the unprecedented sensitivity of the Mid-Infrared Instrument (MIRI) onboard the NASA/ESA/CSA James Webb Space Telescope in the thermal...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have detected silicate clouds in the atmosphere of the exoplanet YSES-1c and a circumplanetary...
Astronomers using ESO’s Very Large Telescope (VLT) have captured spectacular images of an exceptionally structured planet-forming disk around the star...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have detected water, carbon monoxide, and silicon monoxide in the dayside atmosphere of WASP-121b...
Sub-Neptunes are high-occurrence exoplanets that have no solar system analog. Much smaller than gas giants and typically cooler than hot-Jupiter exoplanets,...
The newly-discovered planet orbits at an angle of 90 degrees around 2MASS J15104786-2818174 (hereafter 2M1510), an eclipsing binary composed of two equal-mass...
Using data from NASA’s Transiting Exoplanet Survey Satellite (TESS), astronomers at MIT have discovered a rocky exoplanet orbiting the bright K-dwarf...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have detected the chemical fingerprints of dimethyl sulfide (DMS) and/or dimethyl disulfide...
Proxima Centauri’s flaring activity has been well known to astronomers using visible wavelengths, but new observations with the Atacama Large Millimeter/submillimeter...
