From It’s OK to be Smart.
Why are trees and other plants green? Seems like a simple question. But the answer is full of surprises. Using a special camera that can pick up light just beyond the visible range, into the near-infrared, you’ll get to see trees like you’ve never seen them before. And these other-worldly images can teach us not only why trees are green on Earth, but what color photosynthetic life on other planets might be.
