The Perseid meteor shower sparks the skies this weekend.

There’s no wrong way to watch the Perseids. At peak, there may be up to 50 meteoroids shooting through the sky per hour. Though they mostly appear to come from the constellation Perseus, you’ll be able to spot streaks all over the sky. These flashes are leftover bits of debris from the comet Swift-Tuttle, which crosses the Earth’s orbit during the summer. The comet’s leavings hit our atmosphere at more than 200,000 kilometers per hour, generating spectacular bursts.
