Annual Perseid Meteor Shower, 2009
Google celebrates the Perseid meteor shower today with meteor shower logo on all its home pages. The shower is annually seen from August 8th to 14th, peaking today (August 12).
According to Wikipedia:
The Perseids are a prolific meteor shower associated with the comet Swift-Tuttle. Meteor showers occur when Earth moves through a meteor stream. The stream in this case is called the Perseid cloud and it stretches along the orbit of the Comet Swift-Tuttle. The cloud consists of particles ejected by the comet as it passes by the Sun. Most of the dust in the cloud today is approximately a thousand years old.
The shower is visible from mid-July each year, with the greatest activity between August 8 and 14, peaking about August 12. During the peak, the rate of meteors reaches 60 or more per hour. They can be seen all across the sky, but because of the path of Swift-Tuttle’s orbit, Perseids are primarily visible in the northern hemisphere.
