For Scientists

This page and the set of links available from this page are for the use of scientists who would like to learn more about using Webb for their research programs. 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.)

Visit STScI's website for scientists. There you will find a wide range of performance and simulation tools including an exposure time calculator, image/spectroscopy simulators, and data analysis tools.

Here are fact sheets about JWST and various Solar System Observations from STScI. They are in PDF format:
