In a new theoretical paper, researchers from the Santa Fe Institute provide a new perspective on the origin of life by arguing that life has emerged many...
Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) have studied large, long-duration flares in white light on red dwarfs, a class...
The L 98-59 planetary system contains two non-transiting planets and three transiting terrestrial planets, one of which is a warm rocky world with half...
Astronomers with the COol Companions ON Ultrawide orbiTS (COCONUTS) program have directly imaged a massive exoplanet orbiting the low-mass red dwarf L...
Astronomers from the Giant Outer Transiting Exoplanet Mass (GOT ’EM) Survey have discovered a long-period giant planet circling the 7.4-billion-year-old...
Using the Keck Planet Imager and Characterizer (KPIC) on the Keck II telescope at the W.M. Keck Observatory, astronomers have obtained and analyzed the...
Astronomers using ESO’s Very Large Telescope have detected the isotopically substituted carbon monoxide, 13CO, in the atmosphere of the young giant exoplanet...
Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) have discovered four exoplanets orbiting TOI-2076 and TOI-1807, a pair of related...
Earth’s sphere tilts on its axis at an angle of 23.5 degrees; this gives us our seasons, with parts of the planet receiving more direct sunlight in summer...
Using data from NASA’s Kepler/K2 mission, astronomers have detected four new microlensing events that are consistent with free-floating planets of similar...
In a study to be published in the Astronomical Journal, astronomers found that many exoplanet-hosting stars identified by NASA’s Transiting Exoplanet...
Terrestrial planets (Mercury, Venus, Earth, and Mars) are differentiated into three layers: a metallic core, a silicate shell (mantle and crust), and a...
Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) have discovered a transiting hot-Jupiter exoplanet around a slightly evolved star...
A team of astronomers from Cornell University and the American Museum of Natural History has identified 1,715 stars within 100 parsecs (326 light-years)...
