In 2025, astronomers in the U.S. and around the world continued to make scientific breakthroughs with the Hubble and James Webb space telescopes, along with dozens of missions whose data are publicly accessible in the Barbara A. Mikulski Archive for Space Telescopes (MAST). Researchers also continued to learn about and get excited for the soon-to-launch Nancy Grace Roman Space Telescope — and began preparing for the next great flagship telescope, the Habitable Worlds Observatory. Staff across the Space Telescope Science Institute (STScI) help make this possible. We support these missions and the astronomical community every day. You may also have encountered many of our compelling headlines, since we work to share astronomers’ jaw-dropping discoveries with the world. Explore the institute’s 2025 highlights in our image- and information-packed article and poster.
