Backyard stargazers get a monthly guide to the northern hemisphere’s skywatching events with “Tonight’s Sky.” In April, Saturn reaches opposition and the Lyrid meteor shower streaks through 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. Visit Tonight’s Sky on HubbleSite. hubblesite.org
