“Chemical Fingerprints” Could Help Scientists Recognize Life on the Surface of Exoplanets

A new catalog of reflectance spectra for a diverse range of pigmented microorganisms may help scientists recognize life on the surface of planets orbiting stars beyond our solar system. A team of astronomers and biologists has recorded the “chemical fingerprints” of 137 different species of microorganism. In future, this could help to recognize life on […]
