This new image of Saturn, taken with the Near-Infrared Camera (NIRCam) onboard the NASA/ESA/CSA James Webb Space Telescope on June 25, 2023, serves as...
Planets form in dusty, gas-rich circumstellar disks around young stars, while at the same time, the planet formation process alters the physical and chemical...
Circumbinary planetary systems contain planets that orbit around two stars in the center instead of just one, like in our Solar System.
An artist’s rendition...
NASA’s Kepler space telescope was responsible for the discovery of over 2,700 confirmed extrasolar planets, more than half of the total number of exoplanets...
Saturn’s ring system may well have formed when dinosaurs were still walking on the Earth, and will last only another few hundred million years at most,...
The most feasible explanation is that icy ring particles raining down onto Saturn’s atmosphere cause this heating, according to a team of astronomers...
The radar properties of icy satellites of Jupiter and Saturn commonly differ by more than an order of magnitude from those of rocky planets because of...
Gas giants, like other planets, form from protoplanetary disks of material around protostars. According to core accretion theory, they first form a core...
Astronomers using NASA’s Infrared Telescope Facility (IRTF) telescope at Mauna Kea Observatory have captured and analyzed visible and near-infrared reflectance...
Saturn is known for its iconic, pristine rings. However, the main B ring can have splotches and streaks of darker or lighter material, known as spokes,...
Using data from NSF’s Karl G. Jansky Very Large Array (VLA), the Atacama Large Millimeter/submillimeter Array (ALMA) and NASA’s Juno spacecraft, two...
While the NASA/ESA/CSA James Webb Space Telescope and other space telescopes previously have revealed isolated ingredients of the atmosphere of WASP-39b,...
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...
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...
Barium, a chemical element with the symbol Ba and atomic number 56, is the heaviest element detected to date in any exoplanetary atmosphere.
This artist’s...
Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) have discovered a Jovian planet orbiting the M4-type dwarf TOI-5205. Their paper...
The high-temperature planetary-scale-sized structure is at least 130,000 km (80,778 miles) long, according to a new study led by JAXA scientists.
