One of the year's best meteor showers is well underway, as a new video shows.
NASA's All-Sky Fireball Network captured Perseid meteors streaking overhead on Saturday and Sunday (Aug. 8 and Aug. 9). The footage, which you can see here, serves as a reminder to head outside for the famous Perseid shower, which is expected to peak overnight Tuesday to Wednesday (Aug. 11 to Aug. 12).
The Perseids appear between July 17 and Aug. 24, as Earth plows through debris shed over the eons by Comet Swift-Tuttle. The meteors seem to emanate from the constellation Perseus, hence the name.
The Perseids usually put on a memorable show, with observers under clear, dark skies typically spotting 45 to 90 meteors per hour during the shower's peak. This year is shaping up to be subpar, however. The last-quarter moon will hover low over the horizon in the predawn darkness during the Perseid peak, drowning out some meteors with its glare.
Still, you'll be able to spot some Perseids in the coming days, if your skies are clear and your patience holds. You don't have to know where Perseus or any other constellations are; just go outside, preferably after midnight, and look up. Let your eyes adjust to the darkness, then wait for faint streaks of light to appear.
The All-Sky Fireball Network (opens in new tab) is a system of 17 skywatching cameras around the country that NASA uses to track meteors that blaze more brightly than Venus in the sky. (That's the definition of a fireball, after all.) The agency uses this information to better understand material zooming around near Earth, such as cometary debris.
