Eventually, though probably not in my lifetime but this is how we’ll find life on other planets. We’ll be able to build telescopes powerful enough to see it. Kepler is finding planets left and right, all over the place. At some point, there’s going to be a space-based telescope that’ll be able to zoom right in to discern extraterrestrial forests and fields.
It’s amazing that we built technological solutions to examine (for example) Mars close up, when a telescope like this might have answered all the questions. :’)
