Explanation:
Observing meteors under the moonlight is also a beautiful sight. Look at the Perseid meteor shower!
A dark sky provides excellent conditions for viewing meteor showers. Although the moonlight illuminated the sky this week, stargazers around the world could still enjoy the annual Perseid meteor shower. The waning crescent moon at the end of the lunar month rose at midnight on August 13, slightly later than the predicted peak of the meteor shower. In the image, the moon hangs high over the rocky peaks of the Alborz Mountains in the Firouzkooh region of Iran, with a barren desert landscape in the foreground. A Perseid meteor streaks across the moonlit sky between the overexposed moon and Jupiter in the upper right. The Perseids are a regular annual astronomical event in the Northern Hemisphere; during this time each year, the Earth passes through the dust particles left in orbit by Comet Swift-Tuttle, creating the phenomenon of a meteor shower.
