Earth's mantle is a restless, enigmatic engine that powers volcanism, recycles crust, and regulates the long-term evolution of the planet. But one of its most elusive characteristics—the redox state, or the balance of oxidized ...
A new paper led by a York University professor and published today in Nature Astronomy introduces a simple theoretical framework to describe the evolution of the coupled interior–atmosphere system of hot rocky exoplanets ...
In a study published in Science Advances, scientists have used new lithium isotope (δ7Li) data to show that continental clay export promoted organic carbon burial and thus atmospheric oxygenation during the Cambrian period.
Enhanced rock weathering—a nature-based carbon dioxide removal process that accelerates natural weathering—results in significantly higher first year crop yields, improved soil pH, and higher nutrient uptake, according to ...
Last September, NASA purposefully smashed a spacecraft into Dimorphos, a 160m-wide space rock orbiting a larger asteroid named Didymos. The goal of the mission, called DART (the Double Asteroid Redirection Test), was to demonstrate ...
Global warming has been attributed to the sharp increase in heat-trapping greenhouse gas emissions, in particular CO2 emissions. Carbon capture technology, such as using adsorbents to capture and store CO2 from ambient air, ...
The first experiments with glacial rock flour from Greenland show that it can capture significant amounts of CO2 and provide a wider array of nutrients than commercial organic fertilizers, resulting in improved crop growth. ...
The James Webb Space Telescope (JWST) captured images of a brown dwarf with silicate particles in its atmosphere. In their paper posted on the arXiv preprint server, astronomers describe their analysis of the brown dwarf ...
Water is essential for life on Earth and other planets, and scientists have found ample evidence of water in Mars' early history. But Mars has no liquid water on its surface today. New research from Washington University ...
Brown dwarfs are the cosmic equivalent of tweeners. They're too massive to be planets and too small to sustain nuclear fusion in their cores, which powers stars. Many brown dwarfs are nomadic. They do not orbit stars but ...
