We still don’t know if there is life elsewhere in the universe, but scientists are working on techniques to better understand how it may have originated anyway, in the event that such alien biology […]

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.
