The James Webb Space Telescope (JWST), whose launch is planned for 2013, will be able to see further and better than Hubble currently does, and will study the first stars and galaxies that formed just after the Big Bang.

When scientists are looking into space, the more they can see, the easier it is to piece together the puzzle of the cosmos. The James Webb Space Telescope’s mirror blanks have now been constructed. When polished and assembled, together they will form a mirror whose area is over seven times larger than the Hubble Telescope’s mirror.
