The atmosphere of Earth during the Mesozoic era, between 252 and 66 million years ago, contained far more carbon dioxide than it does today and total photosynthesis...
Sub-Neptunes are high-occurrence exoplanets that have no solar system analog. Much smaller than gas giants and typically cooler than hot-Jupiter exoplanets,...
NASA’s Curiosity rover has found evidence of a carbon cycle on ancient Mars, bringing scientists closer to an answer on whether the planet was ever capable...
Astronomers using the Near-Infrared Camera (NIRCam) onboard the NASA/ESA/CSA James Webb Space Telescope have captured coronagraphic images of the HR 8799...
A team of planetary researchers led by Caltech has determined the chemical mechanisms by which the ancient Mars was able to sustain enough warmth in its...
Planetary scientists using the High Resolution Stereo Camera on ESA’s Mars Express spacecraft have captured stunning images of an enigmatic landscape...
A new class of atomically dispersed nickel catalysts directly converts captured carbon dioxide (CO2) to methane (CH4), according to Dr. Tomaz Neves-Garcia,...
Carbonate minerals are of particular interest in paleoenvironmental research as they are an integral part of the carbon and water cycles, both of which...
Centaurs are former trans-Neptunian objects that have been moved inside Neptune’s orbit by subtle gravitational influences of the planets in the last...
Using data from the Near-Infrared Spectrograph (NIRSpec) onboard the NASA/ESA/CSA James Webb Space Telescope, astronomers have detected carbon dioxide...
Geological observations of Mars indicate a dense early atmosphere ranging from 0.25 to 4 bar of carbon dioxide. But 3.5 billion years ago, the Martian...
A new biomaterial called C-ELM incorporates living cyanobacteria into translucent panels that can be mounted on to the interior walls of buildings. As...
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,...
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....
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....
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have detected abundant water, carbon monoxide, carbon dioxide, hydrogen cyanide and acetylene...
The end-Cretaceous mass extinction, which included the elimination of all non-avian dinosaurs, occurred after the impact of the Chicxulub asteroid and...
Atomic oxygen is produced on the dayside of Venus by photolysis of carbon dioxide and carbon monoxide.
Atomic oxygen is a key species in the mesosphere...
Venus is the least understood of the terrestrial planets. Despite broad similarities to the Earth in mass and size, Venus has no evidence of plate tectonics...
