Backyard stargazers get a monthly guide to the northern hemisphere’s skywatching events with “Tonight’s Sky.” May is a great month for eclipses, both lunar and solar! And the Eta Aquarid meteors are here to shower the night with lovely sights.

“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.
