Planet color may suggest alien life
HEIDELBERG, Germany, Feb. 11 (UPI) -- The light signatures of lichens and algae reflected in a distant planet's distinctive coloring could be evidence of alien life, German researchers say.
Seen from space, Earth gives off a large amount of near-infrared light reflected off the chlorophyll in plants, and similar light wavelength might be seen on distant exoplanets if they also host green vegetation, they said.
