The five artificial greenhouse gases identified by University of California, Riverside astrobiologist Edward Schwieterman and his colleagues would be detectable...
Jupiter’s upper atmosphere is composed of a neutral thermosphere and charged ionosphere. Astronomers using the NASA/ESA/CSA James Webb Space Telescope...
Jupiter’s Great Red Spot is probably the best known atmospheric feature and a popular icon among solar system objects. Its large oval shape, contrasted...
A warm-Neptune exoplanet called GJ 3470b (Gliese 3470b) is 96 light-years away and circles a 2-billion-year-old red dwarf star in the general direction...
About 2.5 billion years ago, free oxygen first started to accumulate to meaningful levels in Earth’s atmosphere, setting the stage for the rise of complex...
Using NASA’s Transiting Exoplanet Survey Satellite (TESS) and many other telescopes, two teams of astronomers have discovered a temperate, Earth-sized...
A surprisingly low amount of methane and a super-sized core hide within WASP-107b, a super-Neptune exoplanet approximately 212 light-years away in the...
Gas giant exoplanets around bright nearby stars provide crucial insights into planetary system formation and evolution mechanisms. Most of these planets...
An ultra-weak geomagnetic field between 591 and 565 million years ago (Ediacaran period) coincided with a significant increase in the oxygen levels in...
Gas bubbling up from a lava-covered surface on the super-Earth exoplanet 55 Cancri e may feed an atmosphere rich in carbon dioxide or carbon monoxide,...
Despite its Earth-like size and source material, Venus is extremely dry, indicating near-total water loss to space. Using computer simulations, planetary...
WASP-43b is cloudy on the nightside and clear on the dayside, with equatorial winds howling around the planet at 8,050 km per hour (5,000 mph).
This artist’s...
Sulfur and chlorine isotopes in Io’s atmosphere indicate that it has been volcanically active for the entire 4.57 billion-year history of the Solar System.
This...
In August 2021, the ESA/JAXA Mercury-bound BepiColombo spacecraft performed its second flyby of Venus and provided a short-lived observation of its induced...
Using data from ESA’s Characterising ExOplanet Satellite (CHEOPS) and several other ESA and NASA missions, astronomers have detected signs of the rainbow-like...
Planetary scientists have long speculated about the potential habitability of Venus, not at its hot surface, but in the cloud layers located at 48-60 km...
The tricarbon molecule (C3) is likely produced in the upper atmosphere of Titan by the reaction of abundant acetylene with atomic carbon.
This view of...
The many large storms and small white clouds seen in the new Hubble images, taken on January 5 and 6, 2024, are evidence for a lot of activity going on...
