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.

Early Universe Crackled With Bursts of Star Formation, Webb Shows

June 05, 2023

$Thousands of small galaxies are scattered on a black background. Some are noticeably spirals, either face-on or edge-on, while others are blobby ellipticals. Many are too small to discern any structure. A few spirals are bluish, but most of the galaxies appear yellow or red. A handful of stars display eight-point diffraction spikes.$

The #JWST Town Hall at #AAS242, starting today at 6:30 pm (MDT), will feature speakers from the JWST Project at NASA’s GSFC & STScI. Topics include a project update, the Cycle 2 selection process & Cycle 3 timeline, the public outreach process, and more. @AAS_Office

If you’re attending #AAS242 in person, stop by the @SpaceTelescope exhibitor booth during regular booth hours to speak with a #JWST expert or pick up the June 2023 edition of the JWST Pocket Guide. @AAS_Office

With Cycle 3 proposals due on October 27, we’re kicking off #JWST events at #AAS242 with a JWST Proposal Planning Workshop on Sunday, June 4th from 8:30 am-5 pm (MDT). The workshop will provide an overview of proposal and planning tools, focusing on ETC and APT. @AAS_Office

Don’t miss #JWST events at #AAS242 in Albuquerque, NM from June 4-8. We’re hosting a Proposal Planning Workshop on June 4 and the JWST Town Hall on June 5. You can also visit the @SpaceTelescope Exhibitor Booth and check out the special session on June 6. @AAS_Office

#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
