Mercury Transit Viewing at Dearborn Observatory


Mercury's transit across the sun can be viewed with Northwestern astronomers at Dearborn Observatory.

A transit of Mercury takes place when the planet Mercury comes between the Sun and the Earth, and Mercury is seen as a small black dot moving across the face of the sun.

The observatory event is free and open to the public. Come any time during the listed hours. Unfortunately Dearborn Observatory is NOT ADA-accessible. Several staircases must be climbed in order to reach the telescope.

This event is weather-permitting. If the weather is questionable, please check the Facebook Event for updates.

This event is sponsored by CIERA, Northwestern University's Center for Interdisciplinary Exploration and Research in Astrophysics.
