Will the James Webb Space Telescope Reveal Another Earth?

With the December 2021 launch of the James Webb Space Telescope, one of the most expensive and ambitious scientific initiatives ever attempted commenced operations. Now that the telescope has been successfully deployed in its unique position in space, its advanced instruments will be able to gather data on questions that scientists once could only dream of answering. Is there life on other planets? How do supermassive black holes mold the mass in their galaxies? JWST may soon be able to tell us....
