Scientists have discovered a vast network of salty aquifers beneath the surface of Antarctica, thanks to an airborne imaging system used there for the first time. The finding may have interesting implications for the […]

Scientists Create Color-Based Catalog of Earthly Life Forms to Help Search for Alien Biology

A hypothetical rendering of colorful plant life on a habitable exoplanet. Although most such alien life, if it exists, found with this technique may be microscopic, it illustrates how analysis of color could help scientists learn more about the physical nature of alien biology.
