By Laurie J. Schmidt, NASA's Jet Propulsion Laboratory Science is full of serendipity -- moments when discoveries happen by chance or accident while researchers are looking for something else. For example, penicillin was identified when a blue-green mold grew on a Petri dish that had been left open by mistake. Now, satellite instruments have given climate researchers at NASA and other research institutions an unexpected global view from space of a nearly invisible fluorescent glow that...

NASA Scientists Use Satellites To Measure Plant Health

NASA [ Watch the Video Seeing Photosynthesis from Space ] NASA scientists have established a new way to use satellites to measure what's occurring inside plants at a cellular level. Plants grow and thrive through photosynthesis, a process that converts sunlight into energy. During photosynthesis, plants emit what is called fluorescence -- light invisible to the naked eye but detectable by satellites orbiting hundreds of miles above Earth. NASA scientists have now established a method...
