I wonder if with the Webb Telescope we can find out signs of intelligent life (i.e. if the habitat/civilization, assuming it has any). For example, if they have artificial satelittes around its orbit like we do.
"JWST’s oxygen-spotting prospects may be dim, but Joshua Krissansen-Totton, an astrobiologist at the University of Washington, thinks there is a good chance that the telescope will be able to detect two other molecules that would suggest the presence of life: carbon dioxide and methane. It will be possible to spot those molecules in a planet’s atmosphere, Krissansen-Totton explained, because they emit light in the infrared portion of the spectrum."

"'Webb will definitely have the capacity to detect water on a rocky planet,' said René Doyon, an astrophysicist at the Université de Montréal who is one of the scientists in charge of building JWST. "
