Space view of San Diego and Tijuana

Commander Chris Hadfield, a Canadian astronaut in Earth orbit aboard the International Space Station, has been tweeting eye-catching photos of points all across the planet. This view from several days ago captures San Diego and Tijuana blending together. La Jolla is to the left of the urban area, and to the right the coast highway of Baja California heads south into Mexico, toward Rosarito and Ensenada.
