Even though many physics teachers take their students on a calculation adventure through circular motion and Newton’s universal law of gravity to determine Earth’s velocity, most of us leave it at that. We present the final result and say, “Look, Earth is moving around the Sun at about 107,000 km/hr (66,000 mph), yet we can’t feel the motion at all!” Well, thanks to an NSF-funded Research Experience for Teachers, some eager participants, a simply built radio horn telescope pointed at the center of the Milky Way, and the addition of Doppler effect considerations, we can verify our calculations through observation… science!
