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...
Using high-precision spectroscopic observations from the Near Infrared Imager and Slitless Spectrograph (NIRISS) onboard the NASA/ESA/CSA James Webb Space...
At the end of their main-sequence life span, stars similar in mass to our Sun will undergo a period of evolution. This stellar evolution is predicted to...
The new map of WASP-18b, a hot-Jupiter exoplanet located approximately 325 light-years from Earth, reveals an atmosphere with distinct temperature zones...
The binary stellar system TOI-2267 likely harbors two warm Earth-sized exoplanets and an additional Earth-sized candidate, according to a new paper published...
Gliese 251 is an early red dwarf star and the 74th closest star system to our Sun.
An artist’s conception of the Gliese 251 system, showing Gliese 251c...
The discovery of 1I/Oumuamua, 2I/Borisov and 3I/ATLAS showed that significant numbers of interstellar objects populate interstellar space. Their omnipresence...
Cha J11070768-7626326 (Cha 1107-7626 for short), a young, isolated exoplanet between 5 and 10 times the mass of Jupiter, has experienced a record-breaking...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have found evidence for the deposition of energy into the upper atmosphere of the nearby...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have found the carbon-rich disk surrounding CT Cha b, a giant exoplanet around 620 light-years...
Using data gathered by NSF’s Gemini South telescope and the NASA/ESA/CSA James Webb Space Telescope, astronomers have detected signatures of methane...
Astronomers are working their way through the TRAPPIST-1 system with the NASA/ESA/CSA James Webb Space Telescope, demonstrating its unprecedented ability...
Using the SPHERE instrument on ESO’s Very Large Telescope (VLT), astronomers have directly imaged a 4.9-Jupiter-mass protoplanet in a cleared gap of...
In a new study, a team of astronomers from Penn State and NASA’s Jet Propulsion Laboratory analyzed when and where human deep space transmissions would...
A protective atmosphere, a friendly Sun, and lots of liquid water — Earth is a special place. Using the unprecedented capabilities of the NASA/ESA/CSA...
This planet candidate, Alpha Centauri Ab, could be a gas giant, orbiting 1 to 2 times the distance between Sun and Earth, according to two papers to be...
Lava planets are rocky exoplanets that orbit so close to their host star that their dayside is hot enough to melt silicate rock.
Boukaré et al. introduce...
Radiolysis induced by Galactic cosmic rays could provide a viable energy source for microbial metabolism in the subsurface environments of rocky planetary...
