[ Spectroscopy ] [ Photometry ] Spectroscopy with New Worlds Observer Spectroscopic analysis from the starlight, reflected off the planets, will give insight on the composition of the atmosphere. New Worlds is capable of detecting the A-band of O2 (761 nm) in the visible, which is a direct indication for having plant life. We can detect as little as 2% oxygen in an atmosphere, which means that we can detect a planet in the early stages of plant production!
