Search for night on a sleepless planet Thursday at the Kahilu Theatre

The advent and spread of electrical lighting has made it ever harder to find the dark skies valued by professional and amateur astronomers, not to mention lovers of starry skies in general. Dr. Wainscoat tells the story about light pollution and astronomy, with special emphasis on light pollution’s effects on Mauna Kea, the world’s best astronomical observing site. Dr. Wainscoat is an astronomer as well as an accomplished photographer.

Attend the event 7 p.m. Thursday at the Kahilu Theatre, or watch a live webcast via the Keck Observatory website.
