Those weren't alien lights you saw last night. They are called light pillars, which happen during cold temps like we experienced last night into early this morning.

The visual phenomenon is created by the reflection of light from ice crystals in the atmosphere. Local photographer Jay Callaghan is a night owl, and took these beautiful pics below around 1:45 a.m. in the Parkhill Rd West area looking towards Lake Chemong, in Peterborough, Ont..
"Once the clouds rolled in the pillars disappeared, so I was at the right place at the right time," Jay tells us. You sure were.

Scotland: Watch the Sky for a Weather BreakFlickr: madmack66An aurora with arcs in different shades of green

Canada: Go North of the Border for Great ViewsNorthern Lights and illuminated Teepee in Yellowknife, Northwest Territories
Why Go: Areas around pristine Lake Superior in Ontario and Northern Canada's tundra back-country are prime viewing spots.

Iceland: Explore Beyond Reykjavik's City LightsFlickr: ArcticBjarkiIceland's Northern Lights and some city light in background
Why Go: Leave the bustling nightlife of the capital city and head out into the wide open plains of Þingvellir National Park--a UNESCO Heritage Site where the North American and Eurasian continental plates meet to cause a rift valley. Under clear dark skies on a freezing night in early March was where I first witnessed the lights dance across the Icelandic sky. Though the show only lasted for 12-15 minutes, it felt like an hour.
Best Viewing Locations: Outside Reykjavik, Þingvellir National Park, the entire country.

Its location above the Arctic Circle, and within the Northern Lights zone, makes it one of the top places to view shimmering green lights. The town also boasts the world's most northerly university, brewery, and planetarium. You can cruise Norway's fjord-lined coast aboard a Hurtigruten ship and get wake-up calls to head out on the deck when the lights appear.
