The Color of Plants on Other Worlds
By Nancy Y. Kiang
If it isn’t easy being green on Earth, where chlorophyll is well tuned to absorb most of the energy in our sun’s yellow light, imagine the difficulties else where in the galaxy. Plants growing on worlds around cooler, brighter or more tempestuous stars would need to rely on red, blue or even black pigments to survive. That insight offers astronomers new clues about what to look for in their search for extraterrestrial life.
