TRAPPIST-1, an ultracool dwarf star located 38.8 light-years away in the constellation of Aquarius, hosts seven planets. The period ratios of neighboring...
In a new paper published in the Astrophysical Journal, Dr. Ravi Kopparapu of NASA’s Goddard Space Flight Center and colleagues assessed the potential...
Astronomers using Webb’s MIRI (Mid-Infrared Instrument) have imaged Epsilon Indi Ab, a gas giant several times the mass of Jupiter located around 12...
Established in 2006 by the International Astronomical Union, the current definition specifies that to qualify as a planet, a celestial body must orbit...
Astronomers have discovered an exoplanet five times the mass of Jupiter that makes a very peculiar orbit around its star.
An artist’s impression of TIC...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have obtained and analyzed morning and evening transmission spectra of WASP-39b, a hot-Saturn...
The last universal common ancestor (LUCA) is the hypothesized common ancestor from which all modern cellular life, from single celled organisms like bacteria...
LHS 1140b is the second-closest temperate transiting exoplanet to Earth with a temperature low enough to support surface liquid water.
LHS 1140b may be...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have detected trace amounts of hydrogen sulfide in the atmosphere of the Jupiter-sized exoplanet...
Within the uncertainties of involved astronomical and biological parameters, the Drake equation typically predicts that there should be many exoplanets...
Ocean worlds are planetary bodies that have a liquid ocean, often under an icy shell or within the rocky interior. In our own Solar System, several moons...
The five artificial greenhouse gases identified by University of California, Riverside astrobiologist Edward Schwieterman and his colleagues would be detectable...
A warm-Neptune exoplanet called GJ 3470b (Gliese 3470b) is 96 light-years away and circles a 2-billion-year-old red dwarf star in the general direction...
Created as part of the TESS-Keck Survey, the new catalog includes 126 strange planets beyond our Solar System, from rare worlds with extreme environments...
Using NASA’s Transiting Exoplanet Survey Satellite (TESS) and many other telescopes, two teams of astronomers have discovered a temperate, Earth-sized...
A surprisingly low amount of methane and a super-sized core hide within WASP-107b, a super-Neptune exoplanet approximately 212 light-years away in the...
Ultracool dwarf stars are widespread in the solar neighborhood. Nevertheless, their extremely low brightness has left their planetary population largely...
Gas giant exoplanets around bright nearby stars provide crucial insights into planetary system formation and evolution mechanisms. Most of these planets...
