Hi Mark,
Agree ref skills as mentioned on reply to Grant. Professionals are already detecting exoplanet atmospheres and I don’t doubt that amateurs will also be able to in the future.
One of the main thrusts, if not the main thrust, for professional astronomers working in this field is the detection of Earth-like worlds and determining whether or not they might harbour life. An area of interest for amateurs even if there is nothing we can do practically at the moment.
Regards
