Main Lesson Extension Day

On Main Lesson Extension Day (January 17), the 12th grade Optics class travelled to Westford to visit two observatories operated by MIT: Haystack Radio Observatory and Wallace Optical Observatory. At Haystack, the students learned about tracking space debris and imaging black holes, and got a tour inside the "radome" (the giant white geodesic ball) to see the 37 meter radio telescope. At Wallace Observatory, they saw the retractable-roof astronomy lab where MIT students conduct observations, learned about light pollution and how it relates to the spectra of light bulbs they studied in class, and observed the sun through a telescope with a solar filter. It was exciting to hear from working scientists and to see all of the impressive facilities hidden out in the woods so close to Boston.
