Although the iconic Hubble Space Telescope is set to be eclipsed by a telescope three times its size in 2018, the James Webb Space Telescope (JWST), astronomers have already proposed an even more impressive space observatory that would put both of them to shame. And tantalizingly, it could reveal how rare or common life is in the Universe.
