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.
A panning-view...
Intensity data of visible light seen by a camera can be plotted as a 3D elevation landscape. The new computer animation, created by citizen scientist and...
Using the NASA/ESA/CSA James Webb Space Telescope, astronomers have captured a direct image of HIP 65426b, an extrasolar gas giant about 6 to 12 times...
Carbon dioxide is a key chemical species that is found in a wide range of planetary atmospheres.
This transmission spectrum of WASP-39b was captured by...
The two new images of Jupiter were taken with Webb’s Near-Infrared Camera (NIRCam), which has three specialized infrared filters that showcase details...
Planetary rings are often speculated as being a relatively common attribute of giant planets, partly based on their prevalence within the Solar System....
Several images of Jupiter and its moons as well as images and spectra of solar system asteroids from Webb’s commissioning period are now available on...
The NASA/ESA/CSA James Webb Space Telescope has captured the distinct signature of water, along with evidence for clouds and haze, in the atmosphere surrounding...
