As seen on Astronomy Picture of the Day bright moonlight from a Full Moon near perigee illuminates the night and casts shadows in this skyscape from Iran. Taken on August 12, near the peak of the annual Perseid meteor shower the exposure also captures a bright and colorful perseid streak above the shady tree in the foreground. The Perseids trails all point back to the heroic constellation Perseus (Click on the constellation icon above the image to see it outlined). The meteors swept up as planet Earth orbits through dust left behind from periodic comet Swift-Tuttle, the cosmic grains that produce perseid meteors enter the atmosphere at nearly 60 kilometers per second, heated to incandesence and vaporized at altitudes of about 100 kilometers.
