Devil’s Slope, Argentina


154 square miles (400 sq kms) of volcanic area called Devil’s Slope, Argentina, is home to the world’s largest crater field. The Bajada del Diablo field is pocked with at least 100 depressions left by meteorite or comet collisions about 130,000 to 780,000 years ago. After capturing this image of a crater lake there, the photographer wrote, “The Celestial Equator: At the Celestial equator the stars are almost at the same distance from both celestial poles so they seem to travel in a straight line. The South Celestial pole is towards the top left of the photo. The North Celestial pole is below the horizon towards the bottom-right.” Photo by Luis Argerich
