Carl Sagan Institute: By looking at Earth's full natural history and evolution, astronomers may have found a template for vegetation fingerprints - borrowing from epochs of changing flora - to determine the age of habitable exoplanets. Reflection on a leave "Our models show that Earth's vegetation reflectance signature increases with coverage of our planet's surface, but also with the age of our planet," said co-author Jack O'Malley-James, research associate in astronomy at Cornell's Carl Sagan ...
