On Tuesday, April 8th, the Blake Planetarium is featuring 5000 Eyes: Mapping the Universe & Passport to the Universe, a presentation that will teach us all about DESI, a scientific research instrument that measures the light of a thousand galaxies at once. The presentation will go from 7 to 8pm with a live segment focused on the current night skies, including information about the summer triangle, to follow. And everyone will go home with a map of the summer skies. You can purchase your tickets online only, through Eventbrite .
