Articles from the STScI newsletter and annual report, featuring the Nancy Grace Roman Space Telescope, are available below.
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.
The Space Telescope Science Institute's 2025 annual report is live! This publication explores how our 850-plus staff members came together to serve both astronomers and the public throughout the year.
To maximize the scientific utility of data delivered by the upcoming Nancy Grace Roman Space Telescope, the mission's partners will deliver a range of products to the astronomical community. Read about the differences between STScI data products created and available upon receipt of the data, and those created for periodic formal data releases. This article also details data products from mission partners, and links to resources.
Astronomers are encouraged to jump onto the Roman Research Nexus now to explore tutorial-style workflows, understand Roman’s data structures, analyze simulated and test data, and build and test tailored workflows in anticipation of the beginning of science operations in 2027.
In the second half of 2025, STScI staff supported Hubble, Webb, Roman, the Habitable Worlds Observatory, and MAST to enable research. We also continued to produce products that communicate these missions’ scientific discoveries. Find opportunities to collaborate or request support, and learn more about how we cover scientific discoveries.
Join upcoming conferences, workshops, symposia, and other astronomy community events, including Language AI in the Space Sciences and Science with the Hubble and James Webb Space Telescopes, organized by the Space Telescope Science Institute in Baltimore, Maryland. Links and recordings to recent events are included.
STScI will participate in the 247th Meeting of the American Astronomical Society (AAS) in Phoenix, Arizona, January 4 to 8. Throughout the week, members of STScI will be involved in a wide variety of science and technical presentations, press conferences, and more. This article may be updated closer to the meeting date.
