It's that time of year again: the Eta Aquarid meteor shower is scheduled to peak tonight through tomorrow morning, and NASA will be live streaming the annual celestial spectacle beginning at 9PM. Astronomer Bill Cooke will be on hand taking questions from webcast viewers. For those who prefer to catch a glimpse in person, the space agency says (as usual) that your best bet is traveling someplace far removed from bright city lights. The shower will continue through dawn, with NASA expecting between 40 and 60 meteors per hour "under ideal conditions." The Eta Aquarid meteor shower occurs each year as the Earth passes through the debris of Halley's Comet, often resulting in fireballs and other mesmerizing visuals.

Update: NASA canceled the livestream due to poor visibility.
