First a meteor exploded over Russia, followed closely by an asteroid fly-by. Now, two comets are expected to put on a naked-eye spectacle for sky watchers in the Northern Hemisphere.
Up first is Comet Pan-STARRS, which gets its funky name from the telescope credited with discovering it in June 2001: the Panoramic Survey Telescope & Rapid Response System in Hawaii.
The comet is already visible through telescopes in the Southern Hemisphere, and it should swing into view over the Northern Hemisphere beginning around March 8.
