A fireball (bright meteor) streaks the sky above Grand Canyon during the Taurid meteor shower. In this fisheye view (fulldome) the radiant of the meteor shower constellation Taurus, the Bull, appears on the other side where bright planet Jupiter shines over the eastern horizon. The canyon's Desert View watchtower is on the foreground gently illuminated by the setting moon. The Grand Canyon, a World Heritage Site in northern Arizona, USA, is the longest canyon on the Earth, a steep-sided gorge carved by the Colorado River steadily in about 17 million year time span. The canyon is 446 km long, ranges in width from about 6 to 29 km and attains a depth of more than 1.6 km (a mile). Date: Nov. 2012
