STScI recently completed the proposal review and telescope allocation process for JWST Cycle 5. The worldwide astronomical community engaged in an unprecedented brainstorm, setting a new record for proposals received in response to any Call for Proposals by a major observatory. Here, we summarize the review process and the results and offer pointers for Cycle 6 applicants.
Review the list of recommended JWST Cycle 5 Large Proposals, Treasury Proposals, Archival Research Legacy Proposals, and Pure Parallel Proposals, roughly ordered by scientific topic to learn about the exciting new science that these observations will enable.
