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.
Join upcoming conferences, workshops, symposia, and other astronomy community events, including the Rocky Worlds DDT Workshop and 30 Years of STIS and the Future of UV Astronomy, organized by the Space Telescope Science Institute in Baltimore, Maryland. Links and recordings of recent events are included.
STScI recently completed the proposal review and telescope allocation process for Hubble Cycle 34. 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 results, and discuss upcoming changes for Cycle 35 and beyond.
Read summaries about all four of Hubble’s Cycle 34 Large Programs and review a list of Medium Programs. Learn about the exciting new science that will be enabled by the telescope’s upcoming observations.
STScI staff members shared some of the exhilaration and excitement they felt during NASA’s Nancy Grace Roman Space Telescope launch from the Kennedy Space Center in Florida on Sunday, August 30.
Would you like to see your science result become a worldwide press release? See what makes a finding newsworthy, find out how to submit your candidate story to STScI’s news team, and learn how the process works. You may also explore previously published releases for inspiration.
The U.S. congressional Wolf Amendment prohibits NASA from using government funds to support bilateral activities involving the government of the People’s Republic of China and China-affiliated organizations. Learn how this affects STScI’s support of Hubble, Webb, Roman, and MAST.
Submit white papers with compelling scientific ideas for Webb’s Multi-Cycle Treasury programs, which require large allocations of telescope time, by Wednesday, November 4.
In the first half of 2026, STScI staff supported Hubble, Webb, Roman, HWO, and MAST to enable research. We continued to communicate these missions’ scientific discoveries and upcoming impact. Find opportunities to collaborate, request support, and learn how we cover scientific discoveries.
Join upcoming conferences, workshops, symposia, and other astronomy community events, including Surveying the Universe in 4D and the 2026 NASA Hubble Fellowship Program (NHFP) Symposium, organized by the Space Telescope Science Institute in Baltimore, Maryland. Links and recordings to recent events are included.
Read an in-depth article about how STScI directors work with the astronomical community to develop Director’s Discretionary Time (DDT) programs to push scientific boundaries and enable consequential investigations with both Hubble and Webb.
Hubble Wide-Field Slitless Spectroscopy (WFSS) observations remain a key capability for low-resolution spectroscopy of all sources in a field. Slitlessutils version 2.0 is a Python package that replaces aXe for spectral reduction, using a full-forward-modeling approach to simulate WFSS images and extract spectra from Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3) observations.
Read about the community’s overwhelmingly positive response to the call for white papers to support Hubble science in the 2030s, the formation of a new working group, and a new opportunity to submit short science pitches highlighting key Hubble science.
Join STScI at the 248th Meeting of the American Astronomical Society (AAS) in Pasadena, California, June 14 to 18, 2026. Throughout the week, members of STScI will be involved in a wide variety of science and technical presentations, press conferences, and more.
Hubble’s Space Telescope Users Committee (STUC) met in April 2026, discussing mission and instrument statuses, updates about the budget, and science-ready products and tools. The STUC will deliver a full report with recommendations based on the information presented.
Read about “Enriching the Universe,” an ESA conference about science with Hubble and Webb held in Vienna, Austria, in April that brought together over 100 participants from 19 countries and more joining online.
