Sept. 3: Frits Paerels Talk and Remote Observing

On Friday, Sept. 3 some 140 people attended a lecture by Dr. Frits Paerels about missing matter in the universe. Dr. Paerels described how astronomers came to understand that most of the matter in the universe was unaccounted for. Showing beautiful images of clusters of galaxies and simulations of the large-scale structure of the universe, Dr. Paerels described how only 4% of the universe was made out of normal matter and how fully 50% of it hasn't yet been detected.

After this great talk, we were treated to a remote observation by graduate students Neil Zimmerman and Andrew Brown who imaged Stephan's Quintet using the website These observations were a big hit with our regular visitors. Other newcomers were treated to a tour of the observatory on the roof with an exhortation to return soon!
