News A variety of targets will be looked at, including planets and moons within our solar system, various star systems and many galaxies from the early universe, where the high redshift and Hubble’s wavelength range made observations difficult. For exoplanets, the strategy is to look at the atmospheres of big planets first. Smaller ones will follow once the easier targets are well understood. James Webb Space Telescope has to point away from the Sun, so the specific targets for the first months will depend on the launch date (not earlier than 2019). All the data from the early observations will be accessible freely immediately.
