Canada's "hailstorm alley" just produced a storm with a scar visible from space.
Satellite imagery from NASA caught the aftermath of a hailstorm that ripped through a region southeast of Calgary, Alberta on Aug. 20. The scar, roughly 125 miles (200 km) in length, is especially visible because vegetation in the late summer "has matured and greened up," agency officials wrote on Aug. 28.
