sciencehabit writes: Frigid temperatures, dry air, and endless nights should, in theory, make the polar regions top spots for ground-based optical astronomy. So far, Antarctica has been getting all the action, with roughly a handful of optical telescopes peering into the sky from the icy continent. But a new study indicates that the Canadian high Arctic is also a good spot for ground-based optical astronomy. In fact, the great white north offers some practical advantages over the Antarctic.
