A Rain of Fiery Tears

New moon coincides with this year’s Perseid meteor shower

Every day and every night, Earth’s orbit crosses paths with errant bits of cosmic dust and debris, which ignite upon contact with our atmosphere. The larger these meteors, the brighter the blaze and the farther they streak. Most times, seeing a single meteor streaking across the sky is a matter of luck.

However, the regular comings and goings of comets and an asteroid provide us with more predictable meteors. Each year in mid-August, Earth passes through the trail of comet Swift-Tuttle, which orbits our sun every 130 years or so. The resulting meteors, the Perseids, are one of the best showings. Better yet, they peak this year during new moon.

You can see Perseid meteors in any part of the sky, but they all appear to emanate from the constellation Perseus, which rises in the northeast around 11pm. Late Sunday and early Monday offers the greatest concentration; as many as 80 meteors an hour may streak across the sky.

Even now and in the week following the peak, the Perseids deliver smaller counts, ranging from a dozen an hour to 30 or 40 on the 11th/12th and the 13th/14th.

The Perseids are also known as the Tears of St. Lawrence, named after the early Christian martyr Laurentius. In the midst of being tortured upon an outdoor stove, Laurentius cried out to his Roman tormentors, “I am already roasted on one side, and, if thou wouldst have me well cooked, it is time to turn me on the other.” The celebration of the martyr Laurentius’s death and the feast of St. Lawrence on August 10 coincides with the annual peak of fiery tears criss-crossing the skies between August 8 and 14.
