A beach in Southampton, New York, treated with olivine sand Chayenne Moreau The first trial to absorb atmospheric carbon dioxide by adding crushed olivine to the ocean had no adverse effects on the seafloor ecosystem in its first year. While the results of the trial in New York state are promising for this carbon-removal technique,…
NASA’s Curiosity rover has detected more than 20 carbon-containing compounds — including seven never before seen on Mars — in a sample collected from 3.5-billion-year-old clay-bearing sandstones in Gale Crater. A close-up of three holes Curiosity drilled into Martian rock at a location nicknamed Mary Anning in October 2020. Image credit: NASA / JPL-Caltech /…
Using the Near-Infrared Spectrograph (NIRSpec) onboard the NASA/ESA/CSA James Webb Space Telescope, astronomers have characterized the atmosphere of TOI-5205b, an extrasolar gas giant orbiting a small, dim red dwarf star. These observations have revealed an atmosphere unexpectedly poor in heavy elements, raising fresh questions about how such ‘forbidden’ alien worlds take shape and evolve. The…
New computational simulations suggest ice-giant planets like Uranus and Neptune harbor a quasi-one-dimensional superionic state of carbon hydride that could reshape how scientists understand planetary interiors. Illustration of the predicted hexagonal carbon hydride compound under Neptune-like interior conditions. In this structure, carbon forms the outer spiral chains (yellow) and hydrogen forms the inner spiral chains…
