Using the NASA/ESA/CSA James Webb Space Telescope, astronomers have detected water-ice clouds swirling through the atmosphere of Epsilon Indi Ab, a cold...
The TOI-201 system consists of a super-Earth, a warm Jupiter, and a more massive brown dwarf at 5.8-, 53-, and 2,900-day orbital periods, respectively.
An...
A new ‘agnostic biosignature’ method searches for patterns across exoplanets, suggesting alien life could be detected by how it spreads and reshapes...
New Webb observations of two exoplanets TRAPPIST-1b and TRAPPIST-1c show blistering days and frozen nights, offering the first detailed climate maps of...
The Jovian system has four large moons, including the largest moon in the Solar System, Ganymede, whereas the Saturnian system is dominated by one giant...
Using the Near-Infrared Spectrograph (NIRSpec) onboard the NASA/ESA/CSA James Webb Space Telescope, astronomers have characterized the atmosphere of TOI-5205b,...
Using the Immersion Grating Infrared Spectrometer (IGRINS) on the Gemini South telescope at the International Gemini Observatory, astronomers have directly...
Using ESO’s Very Large Telescope (VLT) and VLT Interferometer (VLTI) in Chile, astronomers have directly observed two gas giants emerging from the planet-forming...
Using data from ESA’s Gaia mission and the NASA Exoplanet Archive, astronomers at Cornell University have identified 45 rocky exoplanets in the empirical...
Kepler-51 is a young G-dwarf star hosting three super-puffs and one low-mass non-transiting exoplanet. Kepler-51d, the coolest transiting planet in this...
New observations of L 98-59d, a member of the five-planet system L 98-59, suggest it harbors a vast global magma ocean that traps sulfur deep inside, forming...
An unusual flickering of a young F-type star called Gaia20ehk and an expanding cloud of dust around it suggest that a catastrophic planetary crash unfolded...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have for the first time identified hydrogen sulfide gas in the atmospheres of three gas-giant...
Astronomers have discovered a new exoplanet orbiting the nearby K-dwarf star HD 137010 after detecting a single, shallow transit in the archival data from...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have produced the unprecedented high-resolution images of 24 debris disks —...
A population of free-floating planets is known from gravitational microlensing surveys. None have a directly measured mass, owing to a degeneracy with...
PSR J2322-2650b, an enigmatic Jupiter-mass exoplanet orbiting the millisecond pulsar PSR J2322-2650, appears to have an exotic helium-and-carbon-dominated...
The new observations with the NASA/ESA/CSA James Webb Space Telescope suggest that TOI-561b is surrounded by a thick blanket of gases above a global magma...
