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...
An international team of astronomers, using the radial velocity (RV) method, has discovered a third planet in the planetary system HD 33142.

While the massive atmosphere of Jupiter consists mainly of hydrogen and helium, the key to understanding the gas giant’s formation and evolution lies...
Using the Subaru Telescope and the NASA/ESA Hubble Space Telescope, astronomers have found evidence for a Jupiter-like protoplanet around the young star...
The atmosphere of Jupiter is enriched with heavy elements by a factor of about 3 compared to a protosolar composition. The origin of this enrichment and...
Saturn is unique among planets observed to date in that some of its aurorae are generated by swirling winds within its atmosphere, and not just from the...
A team of professional astronomers and citizen scientists has discovered a giant exoplanet orbiting the G5-type star TOI-2180.
An artist’s impression...
The temperature of a planet’s atmosphere decreases with increasing altitude, unless a shortwave absorber that causes a temperature inversion exists....
Solar system’s gas giants, such as Jupiter, Saturn, and massive exoplanets, were formed via the gas accretion onto the solid cores, each with a mass...
