The European Space Agency's Rosetta Mission to the comet 67/P may be rewriting everything astronomers thought they knew about the nature of comets. The latest high-resolution images of the comet nucleus have astonished scientists around the world, revealing a remarkably jagged, pitted, black as coal surface. It is nothing like the so-called dirty snowball or fluffy ice ball that mainstream astronomers have long envisioned. Most astonishingly, scientists have reported they have not found a single trace of water ice on the comet surface. It is, in the words of mission scientist Holger Sierks, "dry like hell."
