Origins on Ice

Origins on Ice
Origins on Ice From the shadowed craters of Mercury, to the outer edges of the Oort cloud, ice is ubiquitous across our planetary neighborhood. Variations in chemistry, temperature, and pressure have produced the roughly two-dozen types of ice we’ve observed, or expect to see, in our solar system. By reading the stories trapped in their ices, scientists gain valuable insights into the interior evolution and climate regulation of planetary bodies. The graceful contours of this deep crevasse are the result of melting in an Antarctic iceberg. Mint Images–Art Wolfe/Science Photo Library
