STScI has released the first version of JWST Search, a tool built off the modern MAST interface that offers a number of novel features, including real-time display of target name resolution into coordinates before searching; auto-complete suggestions; an improved process to identify and download specific data products; and a new approach to search result organization and display. JWST Search also supports large queries and generates download scripts using curl. Additional details are available in the MAST Mission Search Guide.

This new interface does not replace the MAST Portal; users can continue to access JWST data with their current MAST Portal search workflows and scripts. Researchers using astroquery.mast to search or download data using the Observations module may continue to do so without any change.

Planned observations are not yet available from JWST Search, but will be added in an upcoming version. Until then, JWST Search should not be used for observational duplication checking.

The STScI Archive team will continue to develop JWST Search to enhance the user experience. JWST users are encouraged to try it out and send feedback via email or the MAST Help Desk. Read more about the new JWST Search release in the MAST newsletter.
