Don't miss the Orionid meteor shower peak tonight (Oct. 21-22) as tiny shards of Halley's Comet collide with Earth's atmosphere to carve fiery streaks through the Autumn sky! But will the light cast by the waxing gibbous moon spoil the show?
The Orionid meteor shower activity peaks when Earth travels through the densest section of the debris trail left by Comet 1P/Halley. The comet is currently racing back towards the sun ahead of its next visit to the inner solar system in 2061.
Under perfect dark sky conditions 10 to 20 shooting stars could brighten the night sky each hour as the peak unfolds, according to NASA. However, the light cast by the waxing moon — just four days from being full — will likely reduce the number of visible meteors by hiding fainter Orionids from sight.
Orionid shooting stars will appear to travel away from a point of origin, close to the red star Betelgeuse in the constellation Orion, rising above the eastern horizon an hour before midnight for viewers in the U.S.
When and where to see Orionid shooting stars this October
Your best chance at spotting the fast-moving meteors will come in the hours before dawn on Oct. 22, after the moon has set and the radiant approaches its highest point in the night sky. It's best not to stare directly at the radiant, where the glowing meteor trails will be relatively short compared to those left by shooting stars that appear 45-90 degrees away from the bright star Betelgeuse, thanks to an effect known as foreshortening.

Try to travel away from city lights and allow 20-30 minutes for your eyes to adapt to the dark. Always make sure someone knows where you're going if you head somewhere remote to catch the shower and be sure to take a red light to ensure that you can find your way while also preserving your night vision!
