Built in 1999, as part of an initiative to immerse girls in STEM subjects and fields and named after the founder of the first Sacred Heart school in New York City, this is one the few secondary school observatories in New England. During the summer of 2018, the facility was updated with research-grade equipment and capabilities for day and night viewing thanks to a partnership with IBM and NASA. A full-time astronomy teacher and a technician coordinated the installation and the fall 2018 roll-out of a K-12 curriculum.
