Look Beyond: NASA's James Webb Space Telescope

NASA's next great telescope, the James Webb Space Telescope, will be the largest and most complex space telescope ever to launch into space and an engineering feat like no other. As the scientific successor to the beloved Hubble Space Telescope and 100x more powerful, Webb, will look back 13.5 billion years to explore uncharted territories in the first epoch of galaxy formation--a part of our universe never seen before. Webb will also have the amazing capability to study exoplanet atmospheres in unprecedented detail. The tennis-court-sized observatory is designed to answer some of humankind’s most puzzling questions. Built, tested, and assembled by NASA (partnering with the European Space Agency and the Canadian Space Agency) Webb is an international endeavor.
