The dwarf planet Ceres may be a place in our solar system where life could have developed. At 590 miles in diameter it is the largest asteroid and only dwarf planet orbiting the Sun between Mars and Jupiter. Ceres appears to have rocky core surrounded by a thick mantle of water ice which accounts for up to 40% of its volume. How much of Ceres's water, if any, is in liquid form remains to be seen. The mystery of Ceres has deepened by the recent discovery of water emissions coming from this small world.
