The 10 Most Fascinating Astronomy Images of 2025

Dale Dellutri of the Chicago Society for Space Studies leads a low-key, image-by-image tour through ten of the most striking astronomy pictures from NASA's Astronomy Picture of the Day from last year. The presentation, which runs on Monday, October 26, from 6:00 to 7:00 PM at the Harold Washington Library Center, focuses on how the images educate and occasionally function as art—not just science. Dellutri, a longtime amateur astronomer and retired tech professional, brings a patient, explanatory style. Free, and tied to this year's One Book, One Chicago selection, *Orbital*. Advance registration is recommended.
