Often referred to as the successor for Hubble, the James Webb Space Telescope (JWST) is one of the most highly anticipated space telescopes ever built. A large infrared telescope with a 6.5-metre primary mirror, JWST will be able to look at every phase of the Universe, from the period just after the Big Bang to the formation of stars, galaxies, exoplanets and even our own Solar System. Scheduled for launch in fall 2018, JWST recently arrived at NASA’s Johnson Space Center in Houston, Texas, where it will undergo its last, and crucial, cryogenic test.
