The northern lights, you know. It was once a far-fetched life goal just to see them -- involving days-long travel to remote, frozen locations -- but they're now as much a part of your vacation options as the Grand Canyon or Disney World. (Muchas gracias, Icelandair and Alaska Airlines.)
Aspiring aurora borealis viewers now rival the number of residents in Iceland -- so maybe you've already seen them or just want to outshine the masses. Why not make this a challenge, you say. Well, the interplay of Earth's atmosphere and outer space has you covered, fam. Enter: the southern lights.
No, they're not a new country-pop band opening for Florida Georgia Line. The southern lights (or aurora australis) are the same electromagnetic phenomenon as the northern lights, but at the South Pole. The world hasn't beaten a path to see them yet because unlike the northern lights -- visible regularly from Alaska, Canada, Russia, Iceland, and occasionally even the lower 48 states -- seeing the southernmost green flashes is really difficult. Only in a remote few places can you reasonably expect to glimpse them, and even then it's not guaranteed. Which is exactly why seeing them is so darned special.
