The annual Leonid meteor shower peaks this weekend on the mornings of Nov. 17 and 18. Once about every 33 years, the shower’s “parent comet” 55P/Temple-Tuttle swings close to the sun and releases loads of fresh dust along its orbit. Earth crosses this dusty trail and we get a Leonid meteor storm with thousands of meteors per hours shooting across the sky. The last time this happened was in 2001, which turned into the most memorable shower of my life so far. Maybe yours, too.
