Plants grown and sustain themselves through photosynthesis—a seemingly invisible process that converts sunlight into energy. Now, NASA scientists have developed a way to measure photosynthesis from satellites with unprecedented detail.
When plants photosyntehsize, they actually re-emit some of the light they absorb as a faint but measurable glow called fluorescence. The more healthy the plant, the greater the amount of light re-emitted. Now, a team from the Goddard Space Flight Center has created maps of fluorescence that are 16 times more accurate than any that have gone before.
