NASA'S JAMES WEBB SPACE TELESCOPE

JWST for Scientists

The James Webb Space Telescope (JWST), NASA's next flagship infrared observatory, developed in partnership with ESA and CSA, successfully launched on December 25, 2021. After deploying in space and alignment and calibration of the mirrors and instruments, JWST began science operations in July 2022.

Accessible to the worldwide scientific community, JWST offers scientists the opportunity to observe galaxy evolution, the formation of stars and planets, exoplanetary systems, and our own solar system, in ways never before possible. This website offers scientists information on proposing for time on JWST as well as the capabilities of the observatory's instruments and modes, data analysis tools and software, and news and events.

#NASAWebb’s first observations of the ocean world Enceladus—a moon of Saturn—are stunning researchers. A water vapor plume jetting from the moon’s surface measures over 20 times longer than the moon itself. And that’s just the beginning: webbtelescope.pub/3pscOo5

Read the #JWST MIRI MRS update on a careful study of the impact the measured MIRI MRS decrease count rate has on science data, as well as on the upcoming pipeline mitigation: bit.ly/3BUjNJt
