Yesterday we held our Internal Symposium, which occurs every semester! Researchers across all career levels had the opportunity to give five-minute talks about their recent work. We can't wait to see you all next time!
Steward Observatory and NOIRLab were pleased to welcome Professor Richard Pogge as their colloquium speaker, taking about his work with the Large Binocular Telescope. Check out the full colloquium coming soon to our YouTube Channel! youtube.com/@StewardObservat…
The PUFFINS mission is a go! NASA has awarded $20M to a Steward Observatory team led by Ramya Anche to build a compact space telescope that will study how interstellar dust alters starlight in ultraviolet--giving new clues to how stars and planets form. bit.ly/4yROn2s
This striking image features NGC 7331, a spiral galaxy approximately 45 million light-years away in the constellation Pegasus, along with several distant companion galaxies. To use these same telescopes, check out a SkyNights event: bit.ly/4snmUU1!
Weather forecast: cloudy! Using the James Webb Space Telescope, Steward Observatory astronomer Brittany Miles watched WISE 0855, the coldest known brown dwarf, and tracked water clouds moving and changing over time: bit.ly/47VN9Hm

Help us find the faintest galaxies in the Universe with the Vera Rubin Observatory at zooniverse.org/rubin! Thank you to Steward Observatory postdoc, Debasish Hazarika, and University of Arizona undergraduates, Abigail Tennyson and Alon Byrne for their hard work on Zooniverse!
Welcome (and welcome back) to Steward Observatory, all new and returning students, faculty, and staff! Here's to a stellar academic year full of discovery, collaboration, and great science ahead!
Dr. CK Chan, a professor at Steward Observatory, was featured in an OpenAI success story about his use of Codex to improve black hole simulations. His simulations test new ideas about the physics in black holes.
