Surface Volatile Composition as Evidence for Hydrothermal Processes Lasting Longer in Triton’s Interior Than Pluto’s
Ocean worlds, or icy bodies in the outer solar system that have or once had subsurface liquid water oceans, are among the most compelling topics of astrobiology. Typically, confirming the […]
Unlocking Early Earth Chemistry: Salt-induced Changes In Polyester Microdroplet Structure
Billions of years ago, Earth was an extremely hostile planet with active volcanoes, a harsh atmosphere, and certainly no life! This prebiotic Earth, however, was filled with a wide array […]
Lightning Strike Creates Phosphorus Material For The First Time On Earth
After lightning struck a tree in a New Port Richey neighborhood, a University of South Florida professor discovered the strike led to the formation of a new phosphorus material. It […]
A Window Into Prebiotic Worlds?
A perspective article published today in Science magazine’s Insights section provides a unique assessment of the study by Dustin Trail and Thomas McCollom contextualizing a new calibration they built to […]
Mercury Helps to Detail Earth’s Most Massive Extinction Event
The Latest Permian Mass Extinction (LPME) was the largest extinction in Earth’s history to date, killing between 80-90% of life on the planet, though finding definitive evidence for what caused […]
Komatiites as Complex Adsorption Surfaces for Amino Acids in Prebiotic Environments, a Prebiotic Chemistry Essay
Komatiites represent the oldest known terrestrial rocks, and their composition has been cataloged as the closest to that of the first terrestrial crust after the cooling of the magma ocean.
We Drink Good 4.5-Billion-Year-Old Water On Earth
Water is crucial for the emergence and evolution of life on Earth.
The Evolution And Spread Of Sulfur-cycling Enzymes Reflect Volcanic Sulfur Sources And The Redox State Of The Early Earth
The biogeochemical sulfur cycle plays a central role in fueling microbial metabolisms, regulating the redox state of the Earth, and impacting climate through remineralization of organic carbon.
Movement Of The Solar System Through The Milky Way’s Galactic Spiral Arms Helped Form Earth’s First Continents
A new study of zircon crystals from two of Earth’s oldest continents indicates that the formation of Earth’s continental crust goes through cycles, with periods of increased crust production roughly […]
