NASA predicts nongreen plants on other planets

NASA scientists believe they have found a way to predict the color of plants on planets in other solar systems. Green, yellow or even red-dominant plants may live on extra-solar planets, according to scientists whose two scientific papers appear in the March issue of the journal, Astrobiology....
