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...
Biologists at the University of Surrey have investigated inter-species variation in particulate matter accumulation, wash-off, and retention on ten broadleaf...
The Sturtian ‘Snowball Earth’ glaciation (717 to 661 million years ago) is regarded as the most extreme interval of icehouse climate in Earth’s history....
Using data from NASA’s Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered and characterized a habitable zone planet orbiting the...
Using the Wide Field Camera 3 (WFC3) instrument onboard the NASA/ESA Hubble Space Telescope, astronomers have detected water vapor in the transmission...
Astronomers using the NASA/ESA Hubble Space Telescope have detected massive cyclones and other dynamic weather activity swirling on WASP-121b, an ultrahot-Jupiter...
Using the NASA/ESA/CSA James Webb Space Telescope, astronomers have detected a brown dwarf with infrared emission from methane, likely due to energy in...
The clouds of Venus are believed to be composed of sulfuric acid and minor constituents including iron-bearing compounds. Respective concentrations of...
Titan, the largest moon of Saturn, has a unique atmosphere that transforms simple gases like methane and nitrogen into more complex organic compounds....
Planets too close to their star are too hot (such as Venus), those too far, are too cold (like Mars), whereas planets in the habitable zone are just right....
