The Leonid meteor shower is expected to peak during the pre-dawn hours of Nov. 17-20.
Leonids are spawned by the comet Tempel-Tuttle. Every 33 years, it rounds the Sun and then goes back to the outer solar system. On each passage across Earth's orbit, Tempel-Tuttle lays down another trail of debris.
To see the Leonids, lie outside in a dark place between midnight and dawn. Point your feet east and look carefully.
