By order of Gov. Gretchen Whitmer, the Bentley is closed to the public and staff through April 13.

We will be unable to respond to requests or fulfill orders until the governor’s orders are lifted.

Please see our full closure announcement here.


As the second oldest building at U-M and a long-time hub for foundational research, the Observatory is a true campus treasure. Maintaining the aging facilities; keeping the on-site museum in top condition; and sponsoring activities for students, local researchers, and the public are costly endeavors.

Giving to the Detroit Observatory can help ensure that this Michigan icon remains a part of the wide- ranging experience that students, faculty, and visitors have come to expect from our great University.

Please support the Observatory by making a gift today.
