The sky is filled with star trails around the north celestial pole. A reflection of the Earth's daily rotation on its axis, star trails are familiar to photographers who fix their camera to a tripod and make long exposures of the night sky. But the imposing forms gazing skyward probably look strange to many denizens of Earth. Found on the Canary Island of Tenerife, they are red tajinastes, rare flowering plants that grow to a height of up to 3 meters.
