Soon we Will Know if there is Life out there in Space.

We are almost able to tell if there is oxygen on exoplanets. We should be able

to determine this with the spectroscope if we can get the host star's glare

diminished. If there is the abundance of oxygen on an exoplanet then it

probably has life as we know it--since it takes abundant vegetation to produce

such amounts of oxygen--and life as we know it to produce carbon dioxide for

those plants.
