The Space Telescope Science Institute in Baltimore, Md., is home to the science programs of the James Webb Space Telescope, Hubble Space Telescope, and other missions.

About the Telescope
The Webb telescope is NASA's next orbiting observatory and the successor to the Hubble Space Telescope. A tennis-court-sized telescope orbiting far beyond Earth's moon, Webb will detect infrared radiation and be capable of seeing in that wavelength as well as Hubble sees in visible light.

Global Partners
Webb's global appeal has been part of its nature since the beginning. In addition to the United States, thirteen countries are involved in building the Webb telescope: Austria, Belgium, Canada, Denmark, France, Germany, Ireland, Italy, the Netherlands, Spain, Sweden, Switzerland, and the United Kingdom. Additional member states in Europe also contribute to the European Space Agency (ESA). NASA is the lead partner on the project, working in conjunction with ESA and the Canadian Space Agency (CSA).

As the lead agency, NASA has overall responsibility for the JWST mission.  ESA’s contributions to JWST include the Near Infrared Spectrograph (NIRSpec), the Mid-Infrared Instrument (MIRI) Optics Assembly, and the Ariane 5 Launch Vehicle.  CSA’s contributions to JWST include the Fine Guidance Sensor (FGS) and the Near Infrared Imager and Slitless Spectrograph (NIRISS).

About the Space Telescope Science Institute
The Space Telescope Science Institute (STScI) is a science center located on the campus of The Johns Hopkins University and operated by the Association of Universities for Research in Astronomy (AURA) for NASA.

It operates the science program for the Hubble Space Telescope and will conduct the science and mission operations for the Webb telescope. It supports other astronomy programs and conducts world-class scientific research.

About the Office of Public Outreach
At the heart of STScI's mission are outreach and education. The Office of Public Outreach (OPO), which created this website, finds innovative ways to share remarkable science discoveries with the public. OPO is a blend of communications professionals and scientists working together to prepare and disseminate the images and animations seen in the news, as well as posters, exhibits, and educational products in print and electronic formats.
