Look Skyward: The Perseids Return

A meteor captured streaking across the sky by Glastonbury Tor in Somerset on 12 August 2010 at the peak of the annual Perseid meteor shower. The Perseids is one of the most prolific showers, often with around 80 meteors an hour during its peak. Nevertheless, meteors are hard to catch on camera: the photographer has used a continuous shooting mode so that the camera was photographing non-stop in order to catch this fleeting image.

The Perseids, the star attraction among annual meteor showers because of their long viewing time in late summer, have returned. These falling stars have been observed around the constellation Perseus for at least 2,000 years, since 36 CE, or earlier in Eastern sources. They are visible from late July to late August. They are visible mainly in the Northern Hemisphere in the east/northeastern sky. This year, a Google doodle commemorated this brightest moment of the amateur star-gazing calendar.

Google gives background on the 2014 Perseids Google doodle here.

You can see a worldwide map on where to look for them according to your location, here. For tips on watching them, go here.

The meteors will peak on Wednesday, 13 August, from 1 a.m. to dawn. A bright moon will interfere with the peak of the Perseid meteor shower, so the best views may be earlier in the week.  Spacedex:
In 2014, The Full Moon on August 10th and the Waning Gibbous Moon occurring on August 12th will have a negative impact on the visibility of the Perseids. Due to the bright moonlight, the fainter meteors may not be visible. It is advisable to observe the meteor shower during the predawn hours on the mornings of August 11, 12, and the 13th. With up to 60-100 meteors per hour predicted, observers may catch several bright meteors streaking along in the night sky.
Stellarium star-gazing freeware shows the Perseids falling according to time and location of the place on earth and spot in the sky; you can download it, set the view to your location, and cycle through times of day/night until you find an optimal viewing window when the moon does not obstruct the view, yet it is still dark.

Watching them is worth the trouble: seeing one meteor, let alone a storm of them, reminds one of ancient star-gazing traditions, and gives a sense of the unity between the earth and the heavens. Although they are just burning space rocks, they have a miraculous effect on the psyche.

Read my earlier post on the myths around falling stars, here. Ancient tradition said that you could wish on these meteors because they represented a moment when the firmament opened and the gods looked down onto our world, knocking some stars down as they did so. Although they are normally deaf to human entreaties, because they are listening at that moment, they will hear your requests.
