Call for White Papers: Multi-Cycle Treasury Program Concepts with JWST
STScI is requesting white papers from the community with compelling scientific ideas for Multi-Cycle Treasury programs that require large allocations of JWST telescope time to complete. The post Call for White Papers: Multi-Cycle Treasury Program Concepts with JWST appeared first on NASA Science .
The Cosmic Origins Community has issued a call for white papers regarding Multi-Cycle Treasury (MCT) program concepts involving the James Webb Space Telescope (JWST). This call is open until November 4th, 2026, at 11:59 pm ET. The goal is to gather compelling scientific ideas that require significant allocations of telescope time, exceeding the typical 300 hours allocated to large programs.
JWST, in its fifth year of regular science observations, has been instrumental in advancing our understanding of the universe, from solar system studies to cosmology. The telescope's capabilities, with its range of instruments and modes, allow for time allocations from a few hours to a few hundred hours. However, the time is right to explore science concepts needing larger allocations.
The white papers should cover any science topic and describe ideas that necessitate telescope time larger than the usual process for the regular Time Allocation Committee (approximately 300 hours). They are limited to 5 pages (using 11-point font or larger, excluding references) and must be submitted as a PDF. The papers should include a title, list of co-authors, abstract, scientific justification, and estimated observing time required.
The submitted white papers will be reviewed by experts from the community who will assess the scientific merit and the justification of the estimated telescope time. These evaluations will be confidential and will aid STScI and the Jupiter Space Flight Center (GSFC) in deciding whether to issue a call for MCT Program proposals. Although STScI will not publish the white papers, authors are free to do so, but must adhere to STScI's guidelines on the use of verbatim extracts from previously published materials.
Authors are encouraged to join the Webb Office Hours session held on August 27th at 11 am EDT, where experts will be available to answer questions related to this call. For any inquiries or issues, the JWST Help Desk should be contacted. The agency advises not to share personal email addresses and reminds the reader of their privacy policy.
