The STScI Newsletter provides articles of interest to the general astronomical community; presents updates on the Hubble Space Telescope, the James Webb Space Telescope, the Nancy Grace Roman Space Telescope, the Mikulski Archive for Space Telescopes, and other initiatives; and announces relevant meetings and workshops.
The items below represent all volumes, issues, and articles within past and current newsletters. You may use the filter bar to search by specific criteria including relevant missions, volumes and the issues within them, and/or keywords.
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.
Read about Roman’s fully defined Galactic Plane General Astrophysics Survey — and all the possibilities for its science.
Learn how to explore Roman’s four fully defined surveys in detail, prepare for the Call for Proposals, and stay up to date with Roman’s progress.
Find resources and details about the Hubble Cycle 34 Call for Proposals, which are due no later than Thursday, April 16, 2026 at 8 p.m. Eastern Daylight Time.
Learn about significant upgrades to the HST Notebook repository that improve the functionality of our Jupyter Notebook tutorials for core workflows with each HST instrument, as well as the DrizzlePac software suite.
The latest Hubble Spectroscopic Legacy Archive (HSLA) release now automatically defines individual targets, groups multiple observations of a single target into associations, and produces a classification for each target. HSLA also provides a human-readable metadata file for each target with key information that can be used to search and further explore the available spectra from the Cosmic Origins Spectrograph (COS) and the Space Telescope Imaging Spectrograph (STIS).
Join upcoming conferences, workshops, symposia, and other astronomy community events, including Atmospheric Escape and Replenishment in Planetary Systems and Language AI in the Space Sciences, organized by the Space Telescope Science Institute in Baltimore, Maryland. Links and recordings to recent events are included.
Nine targets have been officially selected for the Rocky Worlds Director’s Discretionary Time (DDT) program, and the scheduling is underway. Learn why Webb and Hubble are observing terrestrial planets that orbit M-dwarf stars and what these DDT observations mean for long-term exoplanet research.
Learn about planning and scheduling observations for Hubble and Webb science programs, a highly complicated, time-intensive process that requires continuous adjustments and rescheduling. Also learn how to prepare observations that are easier to schedule or have faster turnarounds.
Scientific and engineering development for the future Habitable Worlds Observatory (HWO) is now actively underway with industrial, academic, and international collaborators. An open community event in August brought together scientists, technologists, and policymakers to discuss the state of HWO’s scientific and technological development.
Read about STScI's AI policy and learn about the launch of an internal AI Community of Practice, which will meet biweekly and include structured presentations, unstructured discussions, and opportunities to test the capabilities and limitations of AI tools.
STScI recently completed the proposal review and telescope allocation process for Hubble Cycle 33. As always, we were impressed by the extremely high quality of the proposals, the compelling science, and the dedication, commitment, and integrity of all those involved. Here, we summarize the review process and the results from the Hubble Cycle 33 proposal review and discuss upcoming changes for Cycle 34 and beyond.
Preview a few notable Hubble Cycle 33 Large Programs and review a list of Medium Programs to learn about the exciting new science that will be enabled by these observations.
Learn how STScI staff supported Hubble, Webb, Roman, and MAST to enable research in the first half of 2025. Also find opportunities to collaborate or request support, and learn more about how we cover scientific discoveries.
Hubble’s Space Telescope Users Committee (STUC) met in person in June 2025. Topics included mission status, updates on the budget for NASA Astrophysics missions, and community advocacy. Of special note was the telescope’s reliability and scientific productivity. The STUC will deliver a full report with recommendations based on the information presented.
