Could present-day spectroscopy be able to detect chlorophyll, or an analogue, on an extasolar planet?

In principle, present-day spectroscopic technology could detect the "red edge" of chlorophyll if an extrasolar planet hosts vegetation that functions similar to life on Earth. However, spectroscopic telescopes are currently limited in their resolution and have the easiest time taking spectra for large Juipter-like planets. This limit is slowly dropping, though, and the next generation of telescopes, such as JWST, will hopefully be able to observe such spectra for Earth-sized planets.

What do biosignatures tell us

Lately there has been a lot of talk about biosignatures. I've even come across articles where they talk about using biosignatures to look for life beyond earth in the rocks here on earth by searching for biosignatures of past life in rocks. I'm just…Continue
