Astronomers have discovered a super-Neptune exoplanet orbiting a star in the binary system Gliese 15.
An artist’s impression of two exoplanets orbiting...
Astronomers using NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) have observed an unusually warm, dusty debris disk around BD +20 307,...
Are we alone in the Universe? It comes down to whether intelligence is a probable outcome of natural selection, or an improbable fluke. By definition,...
White dwarfs are dense, burned-out remnants of normal stars. Due to their strong gravitational pull, surface atmospheres of these ancient objects should...
At three locations in the protoplanetary disk around HD 163296, a young star located approximately 400 light-years away in the constellation Sagittarius,...
Astronomers have discovered a massive exoplanet orbiting Gliese 3512 (GJ 3512), an M-dwarf star (red dwarf) located 31 light-years away. Dubbed Gliese...
Astronomers have discovered a hot-Jupiter exoplanet so close to its host star, called NGTS-10, that a year on that planet lasts only 18.4 hours, making...
Yale University astronomers Gregory Laughlin and Malena Rice propose that interstellar objects such as the interstellar asteroid ‘Oumuamua and the interstellar...
Nova Southeastern University’s Professor Jose Lopez and his colleagues from the University of California Davis and the Federal University of Rio de Janeiro...
A team of astrophysicists from Columbia University proposes that the strange long-term dimming of the KIC 8462852 star (also known as Tabby’s star or...
Astronomers using the NASA/ESA Hubble Space Telescope have detected water vapor in the atmosphere of K2-18b, a planet of eight Earth masses in the habitable...
Astronomers from the Red Dots Collaboration have detected three rocky exoplanets orbiting Gliese 1061, which is the 20th nearest star to the Sun. The outermost...
The temperature on the nightsides of short-period gas giants (hot Jupiters) is surprisingly uniform, suggesting the dark sides of these exoplanets have...
Using data from several ground-based telescopes, astronomers found that a nearby star called HR 5183 hosts a giant planet with an orbital period of between...
In a new study, University of Chicago researcher Stephanie Olson and colleagues modeled climates and ocean habitats of different types of extrasolar planets...
Using data from ESO’s High Accuracy Radial Velocity Planet Searcher (HARPS) instrument, a multinational team of astronomers has uncovered evidence for...
LHS 3844b, a 1.3-Earth-radii terrestrial world in an 11-hour orbit around the small nearby star LHS 3844, very likely has little to no atmosphere and could...
WASP-121b is about two times bigger than Jupiter and 1.2 times more massive. Discovered in 2016, the planet is located 881 light-years away in the constellation...
Using data from NASA’s Transiting Exoplanet Survey Satellite (TESS) and several ground-based telescopes, astronomers have discovered three small exoplanets...
