For anyone who has ever wanted to wish upon a shooting star, this weekend is your chance.
Earth is passing through a stream of debris from Halley's Comet that started earlier this week, which create the the annual Orionids meteor shower—though you probably won't see much until a bit later.
The shower should be at its peak the night of Saturday, Oct. 20 until just before dawn on Oct. 21. This year, the moon will be setting at approximately midnight, which will keep the sky darkened enough that—barring cloud cover, which is possible, according to the National Weather Service—you should be able to see up to 15 meteors per hour.
The Weather Channel's hourly forecast for the 15221 and 15218 Zip codes predicts partly cloudy skies through 9 p.m. Saturday and mostly clear skies during the rest of the night, with the best chance for clear skies from 1 to 3 a.m. Sunday.
NASA says the best time to look is before sunrise on Sunday, Oct. 21. That's when Earth encounters the densest part of Halley's debris stream. Wake up a few hours before dawn, go outside and look up. No telescope is required to see Orionids shooting across the sky.
Where to Watch
Your own backyard works. If you are in a subdivision and can't find a piece of sky overhead that isn't washed out by street lights, consider heading over to the tennis courts—but don't turn on the lights!
Live NASA Chat
Join the NASA chat on the Orionids, planets and constellations that brighten October skies. NASA astronomer Mitzi Adams will be answering your questions via live Web chat on Saturday, Oct. 20 from 11 p.m. to 3 a.m.
Too Cloudy, Cold, or You Just Can't Leave the Kids Home Alone?
If it's cloudy where you live, or you don't like the cooler temperatures this late at night (or early in the morning) you can visit the same NASA site for a live video stream of the meteor shower.
What makes this shower so cool?
First of all, it's a show of shooting stars.
Also, there's no question about where to look for this one. Meteor showers get their names from the constellations in the sky where they can be spotted. And what's easier to spot than Orion the Hunter?
There's also something else that's special about this show: With the second-fastest entry velocity of all the annual meteor showers, meteors from the Orionids produce yellow and green colors and occasionally produce an odd fireball.
Obviously, though, you'll have more luck catching the shooting stars if you're in a place not polluted by light.
