The Draconid meteor shower appears each October, and it can produce a big show or a big shrug. Tonight, however, there's reason for hope. The Draconids - expected to peak Monday around sunset - occur annually thanks to the ribbon of space dust left behind by Giacobini-Zinner, a comet that travels around the sun every 6½ years. In October, Earth passes through this dust, and as pieces of filament encounter our atmosphere, light streaks through the sky. What's great about the Draconids is that, although generally more faint, they're slower-moving meteors, so the light trails linger.
