The Comet Cometh

By Ed Downs

First a meteor smacks into Russia, and then, just a few days later, we get a close flyby of a good sized asteroid. In cosmic terms, that asteroid came close enough to give “doomsday preppers” reason to celebrate their decisions. It was close. But it is not all scary news. Astronomers who work with visible light, versus those light bands that can be seen only through the use of special instrumentation, have something to celebrate. It seems as though the summit of Haleakala on the Hawaiian island of Maui, at 10,000 feet above sea level, now sports a telescopic array that promises to be the most powerful survey telescope ever built. “Survey” means a telescope that specifically looks for things, all sorts of things, which may be heading our way. It’s called Pan-STARRS, short for Panchromatic Survey Telescope And Rapid Response System. And is the first of a four telescopes array planned.
