Beyond the Big Sky
For one weekend a month from June through September, MLC will open its observatories to the public at sunset. Each evening will start with a presentation from a guest astronomer, after which you’ll have the opportunity to use your newfound knowledge to better appreciate the night skies as we gaze through MLC’s state-of-the art telescopes.
