Resources for Scientists

The Space Telescope Science Institute website hosts most of the tools and information that scientists will need for proposing for time on the James Webb Space Telescope. These include:

A detailed description of the science capabilities and instruments on Webb can be found in the Space Science Reviews paper (external link) by Gardner et. al. A brief synopsis of the Webb science themes can be obtained here. White papers written by the JWST Science Working Group can be found here.

For technical information about the status, design and plans for Webb, you can go to and search for “webb" and "jwst”. On that site there are more than 500 technical articles about Webb. (Note there is a fee per article on that site without an institutional subscription.)
