Tonight’s Sky: April 2011 Highlights

Backyard stargazers get a monthly guide to the northern hemisphere’s skywatching events with “Tonight’s Sky.” In April, ****** reaches its closest point to Earth, the Big Dipper overflows with cosmic sights, and the Lyrid meteor shower streaks the sky. “Tonight’s Sky” is produced by HubbleSite.org, online home of the Hubble Space Telescope. This is a recurring show, and you can find more episodes — and other astronomy videos — at HubbleSite.org.
