Gas giants, like other planets, form from protoplanetary disks of material around protostars. According to core accretion theory, they first form a core...
Rocky exoplanets orbiting red dwarf (M-dwarf) stars are among the most promising and abundant astronomical targets for detecting habitable climates. Planets...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have detected gaseous water in the planet-forming disk around V883 Orionis, a...
Dr. Lokesh Mishra and his colleagues from the University of Bern and Geneva Observatory propose that the space of planetary system architectures be partitioned...
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 recently announced the discovery of TOI-700e, a habitable-zone, Earth-sized planet some 102 light-years away in the southern constellation...
Princeton Plasma Physics Laboratory physicists Deepen Garg and Ilya Dodin say they can better understand the state of the cosmos shortly after the Big...
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.

Using data from the NASA/ESA Hubble Space Telescope and NASA’s retired Spitzer space telescope, astronomers have discovered that two exoplanets around...
While the NASA/ESA/CSA James Webb Space Telescope and other space telescopes previously have revealed isolated ingredients of the atmosphere of WASP-39b,...
WD J2147-4035, an 11-billion-year-old white dwarf located 91 light-years away in the constellation of Grus, is accreting debris from orbiting planetesimals,...
Using data from NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton spacecraft, astronomers have looked for the effects of massive, close-in planets...
Gliese 1252b, a super-Earth exoplanet that orbits an M-dwarf star 67 light-years away, retains only a tenuous mineral exosphere.
An artist’s impression...
TOI-3757b is the lowest-density transiting exoplanet known to orbit an M-dwarf (red dwarf) star.
An artist’s impression of TOI-3757b and its parent star....
Using data from NASA’s Transiting Exoplanet Survey Satellite (TESS) and several ground-based telescopes, astronomers have detected and characterized...
