On April 22, 2023 we will be celebrating 100 years of discovery with the Steward Observatory Dome and the 36-inch first “All-American” made reflecting telescope,” both still in use today. This telescope is part of the SpaceWatch® Program on Kitt Peak, which monitors objects in space that might present a hazard to Earth.

Celebrating 100-Years of Discovery!

Open House: Learn How Our Discoveries Will Transform Our Understanding of the Universe in the Next Century!
