Hidden Viruses Reshape One Of Earth’s Largest Carbon Systems
Viruses play a far more active role in Earth’s carbon cycle than previously understood, according to new research that reveals how they infect and control microbes responsible for carbon production […]
Analytical Characterization Approaches to Measure Prebiotically Relevant Compounds in High Salinity Impact-Induced Hydrothermal Systems
Experiments exploring potential emergence-of-life chemistry in a laboratory setting critically depend on simulating realistic early-Earth environments. Such experimental conditions include the implementation of controlled high temperatures and pressures, anoxic gas […]
Coupled Photochemical-Climate Modeling of Plausible Tenuous Outgassed Atmospheres on the TRAPPIST-1 Planets
Available JWST observations TRAPPIST-1 system have suggested that several of the planets are likely airless, or possess a very tenuous atmosphere.
In Situ Carbonation of Sedimentary and Igneous Rocks of Ultramafic Composition in Jezero Crater, Mars
Over 3.5 years of exploration in Jezero Crater, the Perseverance rover has explored several geological units of diverse origins and natures, performing multi-technique remote analyses of the chemistry and mineralogy […]
The NCCR PlanetS Closes After 12 Remarkable Years
On Friday, 22 May 2026, scientists from the National Center of Competence in Research (NCCR) PlanetS will meet at the Kursaal in Bern to celebrate the achievements and successes of […]
Coupling Magma-ocean And Atmospheres In Spectral Retrievals Of Sub-Neptunes
Recent high-precision atmospheric observations with JWST is enabling detailed characterization of sub-Neptune atmospheres and motivating efforts to understand and constrain their interiors.
Ice Planet Orbital Recon: Greenland’s Changing Ice
Greenland is the world’s largest island and about 80% of its surface is covered by the Greenland Ice Sheet, the second largest ice mass on Earth after the Antarctic Ice […]
Revisiting the Greenhouse Effect of Non-greenhouse Gases in the Atmospheres of Earth-like Planets
Although non-greenhouse gases can vary substantially in abundance in Earth-like atmospheres, their climatic influences remain insufficiently understood.
Mineral False Positives in the Search for Exoplanet Surface Biosignatures
In the search for life in the cosmos, biopigments on exoplanet surfaces are a critical target.
