What future Vis/IR space-based interferometers will discover
Within the next 30 years, large space-baded visible/IR interferometers equipped with imaging spectrometers will most likely detect "exo-vegetation" on earth-like worlds. Identification of the "red edge" feature of vegetation, or a shifted "red edge" feature, dependent on the type of star, will probably be the first major discovery of a habitable biosphere on another planet outside of our own solar system.
