Unravelling the mysteries of the early universe
Peering far: Unlike the Hubble Space Telescope, the JWST can detect faint infrared radiation coming from very distant sources in the universe. The James Webb Telescope, the next step after the Hubble Space Telescope, is a large, infrared-optimized space telescope, scheduled for launch in 2013. It will find the first galaxies that formed in the early universe and peer through dusty clouds to see stars forming planetary systems.
