Backyard stargazers get a monthly guide to the northern hemisphere’s skywatching events with “Tonight’s Sky.” May features the Eta Aquarid meteor shower, and could feature a meteor storm later in the month as Earth passes through the debris from Comet 209P/LINEAR.

“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.
