San Francisco’s “Urban Astronomer” Paul Salazar will join DJ Marilynn at radio station KPOO to broadcast and stream a guided tour of the glorious night sky. With Paul’s radio and live-stream Internet audio guidance, Bay Area residents will collectively view the setting Moon, Jupiter, and Saturn, as Mars, the Pleiades star cluster, and the Andromeda Galaxy rise in the east. (Folks stuck indoors or under clouds can participate “virtually” via any of several free smartphone astronomy apps.) Find an unobstructed view of the sky, and tune into KPOO-FM (89.5 MHz) or visit https://kpoo.com/stream. Stargazing households congregating in backyards and socially-distanced strangers on sidewalks will feel united by the grandeur — and the wonder — of the night sky.
