Tricorder Tech: Chemistry Modeling Software Used To Detect Conditions For Microbial Life On Icy Worlds
Southwest Research Institute is working to expand software normally used to model electrolytes and predict corrosion and turn it into a tool that can help determine whether ice-covered worlds have […]
A Multiple Biomolecules-based Rapid Life Detection Protocol Embedded In A Rover Scientific Subsystem For Soil Sample Analysis
The study of whether life exists, is extinct, or not depends on various sophisticated experimental studies, as many different signatures of life can be used. The experimental procedures that can […]
The First Amber Found In Antarctica
Roughly 90 million years ago, climatic conditions in Antarctica were suitable for resin-producing trees. A team of researchers led by the Alfred Wegener Institute and the TU Bergakademie Freiberg have […]
Ultraviolet Photometry and Habitable Zones of Over 2700 Planet-Hosting Stars
The ongoing discovery of exoplanets has sparked significant interest in finding suitable worlds that could potentially support life. Stellar ultraviolet (UV; 100-3000 Å) radiation may play a crucial role in […]
Mars Perseverance Rover Observes Red Rocks With Green Spots at Serpentine Rapids – Possible Biosignatures?
Editor’s note: I will make this simple: did NASA find evidence of life on Mars? No. Did NASA find an interesting rock feature that might signal or indicate that there […]
The Detectability of CH4/CO2/CO and N2O Biosignatures through Reflection Spectroscopy of Terrestrial Exoplanets
The chemical makeup of Earth’s atmosphere during the Archean (4 Ga-2.5 Ga) and Proterozoic eon (2.5 Ga-0.5 Ga) contrast considerably with the present-day: the Archean was rich in carbon dioxide […]
Simulated View of Thermal Emissions from Europa
Scientists based this image on a model of data from NASA’s Galileo mission and data from an instrument on NASA’s Cassini mission that studied warm regions of Saturn’s moon Enceladus […]
Hidden Ecosystems Discovered In Earth’s Seafloor Beneath Hydrothermal Vents
The idea of secret worlds beneath the Earth has long been the stuff of science fiction. But new research reveals it’s not as far-fetched as it might appear. Worms and […]
Orbital Biosignature Survey: Algal Bloom In Lake Pyramid
This Copernicus Sentinel-2 image, acquired on 15 October 2024, shows an ongoing algal bloom in Lake Pyramid, Nevada, USA.
