The upcoming extremely large telescopes will provide the first opportunity to search for signs of #habitability and #life on non-transiting #terrestrial #exoplanets.

For the most accessible nearby target, #Proxima Centauri b, we may be able to rule out a sub-Neptune #atmosphere in as little as a single hour of observing, and some #biosignature disequilibrium pairs may be accessible in 10 hours.
