Artist's Concept of the James Webb Space Telescope (JWST)
Peering deep into space and back into time, NASA's James Webb Space Telescope (JWST) will search for cosmic origins, studying objects that existed when the universe was young; when galaxies, stars and planetary systems were being formed. Nascent stars and galaxies are so distant that by the time their light reaches us, it has stretched into the longer, redder wavelengths and is invisible to the human eye. JWST will allow us to see even farther into space beyond the visible-light range into the invisible, infrared spectrum. One of the key components that make these scientific technologies possible is that JWST will be equipped with a larger deployable mirror than the Hubble Space Telescope. This mirror with a suite of revolutionary, infrared-sensing cameras and spectrometers will make JWST an important component of NASA's Origins program.
