James Webb Space Telescope (JWST)

The greatest investment in American space leadership and innovation

TAKE ACTION NOW!
  • LEADERSHIP IN SPACE

    JWST is recognized as the successor to the Hubble Space Telescope and will ensure U.S. leadership in space astronomy for the next decade. The Webb telescope is the cornerstone of future space astronomy as named by the National Academy of Sciences 2010 Astronomy Decadal Survey.

  • NEW FRONTIERS

    There is no mission planned by any other space agency that can achieve the science goals of JWST. These goals are transformative and will open a new era in astrophysics: JWST will find liquid water on planets, reveal the births of stars and planetary systems, and study the evolution of galaxies.

  • BREAKTHROUGH TECHNOLOGY

    The JWST spacecraft unfolds and operates at cryogenic temperatures, orbiting at L2, nearly one million miles from Earth. Webb features a tennis court-sized, five-layer sunshield and a 21.5 ft.-diameter deployable primary mirror, both first of their kind for space telescopes.
