What: an annual celestial light show of "falling stars" or meteors.
When: This year, peak viewing occurs on August 11-12, 2017 beginning at 9:30 PM ET on the 11th, and growing more
spectacular after midnight and into the early morning hours until dawn.
Where: look toward the horizon at the constellation Perseus rising in the northeast sky.
What to bring: lawn chair, bottled water, camera, tripod.
The Perseid meteor shower is an annual meteor shower that is extremely regular in its timing and can potentially be visible for weeks in the late summer sky, depending on weather and location.
The Perseid meteor shower is named after the constellation Perseus, which is located in roughly the same point of the night sky where the Perseid meteor shower appears to originate from. This is a useful
naming convention, but not very accurate!
The source of the Perseid meteor shower is actually debris from the comet Swift-Tuttle. Every year, the earth passes through the debris cloud left by the comet when the earth's atmosphere is bombarded by what is popularly known as "falling stars."
When and where to look for Perseids in 2017
As luck would have it, the Perseid will not be as visible this year as last year, with a visible waning moon in 2017 that will result in less than optimum conditions for viewing the big show.
Because of the way the earth hits this debris cloud, the Perseid meteor shower is much more visible in the Northern hemisphere.
People in Canada, for instance, can see the meteor shower by mid-July, but generally there isn't much activity at such an early date. Throughout Europe, the US and in the rest of North America, meteor shower activity usually peaks sometime around August 12th, when it is not unusual to see at least 60 meteors per hour streaking across the Northeast sky.
The meteors are certainly bright, but they are actually only tiny objects, usually no more than a grain of sand. However, as they travel at speeds of up to almost 45 miles-an-hour per second, these small particles put on quite a brilliant spectacle. Peak temperatures can reach anywhere from 3,000 to 10,000 degrees Fahrenheit as they speed across the sky.
"Woah...did you see that?" The Perseids light and magic show peaks on the night of August 11.
How to view Perseids
Today, the best place to observe the Perseid meteor shower (or any meteor shower for that matter), is somewhere dark, away from light pollution, and with the moon out of the field of vision. The less light visible, the more brilliant the meteor shower will be.
Telescope or camera?
viewable to the naked eye, the annual Perseid meteor show may
be partially obstructed by the moon, clouds or night mist, so
amateur astronomers may want to carry along a pair of binoculars
or a camera with a telescopic lens.
Even on clear nights, some kind of viewing aid comes in handy for catching sight of even the faintest
of falling stars, aptly named "telescopic" meteors.
Experts usually just advise to forget the telescope, and simply look up
toward the northeast sky.
the annual event, a digital camera mounted on a tripod helps to
steady the images that swiftly move across the sky.
A quick trigger
finger also helps. Even random clicks during the height of
Perseid "prime-time" will guarantee that you'll
catch something! Be sure to have the camera focused on infinity
and, if your camera permits, leave the shutter open for several
minutes for the most spectacular photographic effects.
