The First Animals On Earth May Have Been Sea Sponges, Study Suggests
A team of MIT geochemists has unearthed new evidence in very old rocks suggesting that some of the first animals on Earth were likely ancestors of the modern sea sponge.
Minute Witnesses From Earth’s Primordial Sea
Earth scientists often face huge challenges when researching the earth’s history: many significant events occurred such a long time ago that there is little direct evidence available. Consequently, researchers often […]
A Carbon Cycle Flaw Can Plunge Earth Into An Ice Age
UC Riverside researchers have discovered a piece that was missing in previous descriptions of the way Earth recycles its carbon. As a result, they believe that global warming can overcorrect […]
Shocked Quartz At The Younger Dryas Onset Supports Cosmic Airbursts/Impacts
Shocked quartz grains are an accepted indicator of crater-forming cosmic impact events, which also typically produce amorphous silica along the fractures. Furthermore, previous research has shown that shocked quartz can […]
Brine Composition And UV Photochemistry Effects On Halobacterium Salinarum Cell Envelope Biosignature Preservation
Hypersaline environments, including brines and brine inclusions of evaporite crystals, are currently of great interest due to their unique preservation properties for the search for terrestrial and potentially extraterrestrial biosignatures […]
Multiple Episodes of Fluid Alteration in Jezero Crater Indicated by MIST Mineral Identifications in PIXL XRF Data
The Mineral Identification by Stoichiometry (MIST) algorithm can identify mineral species in geochemical data sets. MIST is applied to X-ray fluorescence chemical analyses from the Planetary Instrument for X-ray Lithochemistry […]
ESA Away Team Training: Lunar Geology Lessons For Artemis
Editor’s note: when it comes to conducting field trips – sorties – Away Team missions – on another world, astrogeology and astrobiology and astrochemistry overlap with one another all the […]
The Biology, Microclimate, and Geology of a Distinctive Ecosystem Within the Sandstone of Hyper-Arid Timna Valley, Israel
Microbial endolithic communities in the sandstone rocks of the southern Negev Desert, particularly in Timna Park, were initially discovered by Imre Friedmann and Roseli Ocampo-Friedmann in their pioneering study about […]
Mid-Devonian Ocean Oxygenation Enabled The Expansion Of Animals Into Deeper-water Habitats
The oxygenation history of Earth’s surface environments has had a profound influence on the ecology and evolution of metazoan life.
