The night of May 10, an astounding and rare astronomical view will be seen from the Walkway Over the Hudson: The planets will be clear and visible (with the exception of Venus), creating a "string of pearls" across the heavens. An event will be held at the midpoint of the bridge with renowned astronomer Bob Berman, who will conduct a factual and funny lecture about our solar system, fit with telescopes to provide close-up views of the otherworldly night sky. The event is open exclusively to Walkway members, but annual memberships start at only $40. (845) 454-9649; Walkway.org.
