Geissberger Observatory includes a 16” diameter research telescope, robotic mount, real-time video feed into our astronomy labs, and the best view in the East Bay.

The 56,000 square foot Brousseau Hall is a research and teaching hub that features 17 cutting-edge labs, a seawater Aquarium lab, and four walk-in environmental chambers. There's also a terrific saltwater aquarium, a bevy of public and private study areas, and the finest nautilus-centered design scheme you'll find anywhere.
