Introduction

The Space Telescope Scientific Institute (STScI) scientific staff actively research topics in the Solar System and exoplanets; stars and the interstellar medium; galaxies, the intergalactic medium, and cosmology; instrumentation; and future space telescopes. Our publications and presentations also relate to a range of NASA missions, including the Hubble Space Telescope (HST), the James Webb Space Telescope (JWST), the Wide Field Infrared Survey Telescope (WFIRST), community missions and future concepts, and further analysis of data in the Barbara A. Mikulski Archive for Space Telescopes (MAST), which includes more than 20 missions. This page provides an overview of some of these scientific activities.
