Using NASA’s Transiting Exoplanet Survey Satellite (TESS) and several ground-based telescopes, astronomers have discovered and confirmed a warm super-Neptune...
The newly-discovered planetary core, named TOI-849b, is a gas giant that was either stripped of its gaseous atmosphere or that failed to form one in its...
Astronomers have discovered and validated two small exoplanets orbiting the nearby red dwarf star TOI-1266.
An artist’s impression of the TOI-1266 planetary...
Using data from NASA’s Transiting Exoplanet Survey Satellite (TESS) and Spitzer Space Telescope, astronomers have discovered a transiting hot-Jupiter...
Using three instruments on ESO’s Very Large Telescope (VLT), an international team of astronomers has discovered and imaged a giant sub-stellar object...
Using the Near-Infrared Camera (NIRC2) on the Keck II telescope at W. M. Keck Observatory on Maunakea in Hawaii, astronomers have directly imaged two infant...
NASA’s Juno orbiter captured a beautiful image during its 25th close flyby of Jupiter in February 2020.
This image of Jupiter was taken on February 17,...
Multiwavelength observations from the NASA/ESA Hubble Space Telescope and Gemini Observatory combined with close-up views from NASA’s Juno spacecraft...
Using the High-Resolution Echelle Spectrometer (HIRES) instrument on the 10-m Keck I telescope at W.M. Keck Observatory, astronomers have discovered a...
A team of planetary researchers from the United States and the United Kingdom has created a 2D map of densities and temperatures in Saturn’s thermosphere...
WASP-76b, a gas-giant exoplanet located some 640 light-years away in the constellation of Pisces, has a day side where temperatures climb above 2,400 degrees...
A team of astronomers in Japan has demonstrated that systems can form that have only one large moon, such as Titan around Saturn, around a gas giant.
An...
Super-puffs, an intriguing, growing class of exoplanets, are the objects with exceptionally large radii for their masses and thus correspondingly low densities....
Water makes up about 0.25% (almost three times that of the Sun) of the molecules in Jupiter’s atmospheric molecules at the gas giant’s equator, according...
Astronomers using data from ESA’s Gaia star-mapping satellite have discovered a newborn gaseous exoplanet closer to Earth than any other of similarly...
Using the 10-m Keck II telescope at the W.M. Keck Observatory and Subaru Telescope, a team of astronomers has studied the orbits of 27 long-period giant...
At the end of its mission in 2017, NASA’s Cassini spacecraft performed a set of ‘Grand Finale’ orbits bringing it closer to Saturn than ever before....
A new study, published in the journal Nature Astronomy, suggests that our young Solar System’s protoplanetary disk was divided into two regions: on the...
