This photograph was taken on August 11, 2010 in the Arizona desert, the night before the peak of the Perseid Starfall. In the center of the image we see a meteor crossing the sky.
The Perseids are traces of dust from the Swift-Tuttle comet that come into contact with our atmosphere and disintegrate showing a flash. Its peak reaches up to 100 meteors per hour.
It is the most popular star shower in the northern hemisphere. Curiously, it is not the biggest or the most spectacular of the year, although it is the one that causes the most expectation. They can be seen from mid-July to the end of August, and reach their peak between August 10 and 12.
The name Perseidas has its origin in Greek mythology. Danae was locked up by her father so Zeus couldn't get close to her. But Zeus fertilized her by throwing a shower of gold. Fruit of that rain was born Perseus.
The radiant point of the Perseids, that is, the place where the meteors seem to fall is precisely the constellation of Perseus. Since the Middle Ages, Christianity called the Perseids the Tears of St. Lawrence, because the peak coincided with the feast of the saint.
