Backyard stargazers get a monthly guide to the northern hemisphere's skywatching events with "Tonight's Sky." In May, one of the largest constellations fills the southern 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.
Hubble's Universe Unfiltered is a collection of video podcasts. Each episode offers an in-depth explanation of the latest news story or image from the Hubble Space Telescope, presented by astronomer Frank Summers. Learn more at hubblesite.org.
