John Mather is the senior project scientist behind the Hubble Telescope's successor, the James Webb Space Telescope (JWST). "This telescope extends the science that Hubble has pioneered, but it covers different wavelength regions," he said. The JWST will see in infrared, as opposed to Hubble's scan of optical and ultra-violet wavelengths. Infrared technology will allow astronomers to see farther into the cosmos, giving insight into the farthest, and oldest, regions of outer space.
