A study of crystals like the one shown above – a blue salt crystal, or halite, from the Zag meteorite that fell to Earth in 1998 – has discovered both water and an array of complex organic compounds including amino acids.
Using an X-ray microscope, researchers studied the molecular makeup of the crystals. They believe the meteorite may have originally been seeded by water or ice ejected by volcanic activity on the dwarf planet Ceres.
