Announcement

We are pleased to announce the Cycle 6 Call for Proposals for James Webb Space Telescope (JWST) General Observer (GO), Survey, and Archival Research (AR) programs. We anticipate allocating up to 7,700 hours in Cycle 6 divided proportionally among Very Small, Small, Medium, and Large/Treasury GO programs, depending on proposal pressure. We invite scientists to participate in this opportunity, which is open to all categories of organizations, both domestic and foreign, including educational institutions, profit and nonprofit organizations, NASA Centers, and other Government agencies.

Proposals are due on September 30, 2026 by 8:00 pm US Eastern Time. The APT submission portal will close promptly at the deadline.

The version of the Astronomer's Proposal Tool (APT) required for proposal submission is 2026.3.2 or higher. This version was delivered on July 9, 2026. We encourage prospective investigators to start preparing their proposals as soon as possible.

The Cycle 6 Telescope Allocation Committee (TAC) will meet in the first two weeks of February 2027, with selections announced in March 2027.

For details, please consult this full Call for Proposals, including JWST New Features and Updates. Questions may be submitted to the JWST Help Desk.

The telescope and its instruments were built under the auspices of the National Aeronautics and Space Administration (NASA), the European Space Agency (ESA), and the Canadian Space Agency (CSA). Management of JWST's scientific program is carried out by the Space Telescope Science Institute (STScI).
