Lucky Shot

A Perseid meteor zips over Iran's Alamut Castle in an August 12 picture submitted to the astronomy-education project The World at Night.

The Perseids, which occur annually when Earth and the moon pass through a cloud of rocky particles shed by comet Swift-Tuttle, often provide an impressive show for sky-watchers—including photographer Oshin D. Zakarian.

"Just came back from Perseid-meteor shooting," he wrote with his submission, "and this time I was lucky!"
