Fifty-one Perseid meteors were captured in this composite image of 30-second exposures taken over six hours in 2004. The annual Perseid meteor shower is one of the most visible to the human eye.
Set your alarm clocks. The Perseid meteor shower, the annual celestial lightshow that Space.com com calls the most widely observed and dependable meteor display of the year, will peak tonight and early tomorrow morning.
"If you see one meteor shower this year, make it August's Perseids or December's Geminids," according to the space agency. "The Perseids feature fast and bright meteors that frequently leave trains, and in 2015 there will be no moonlight to upstage the shower."
And Jupiter's positioning this year will make for even better viewing, as the planet's gravitational field can "slightly perturb the comet particles, just enough to nudge them closer to the Earth," Space.com adds.
At peak activity during the shower, the meteor count could be up to 100 meteors per hour, NASA says, with meteors radiating from the direction of the constellation Perseus.
The Washington Post says that "cloud cover forecasts suggest the viewing will be good over much of the Eastern and Western U.S., with the potential for cloudiness from the central Rockies to the Upper Midwest."
NPR's Geoff Brumfiel spoke with Rhiannon Blaauw of NASA's Meteoroid Environment Office last year about tips on watching the Perseids. She told him, "Just lie on your back, look straight up, give your eyes time to adjust to the dark; it takes longer than people think."

As the Two-Way has reported, "The Perseids, the dusty debris of Comet Swift-Tuttle, whisk through our upper atmosphere every August. They aren't the only meteor shower on the calendar, but 'the Perseids are the good ones,' says meteorite expert Bill Cooke of NASA's Marshall Space Flight Center in Huntsville, Ala."
