This is one of the top 2 or 3 largest marbles I've ever seen from Sean, and it is incredibly impressive in hand! This galaxy is in the very early stages of formation, as there is still a lot of chaos and energy roiling around inside the marble, working to spin stars off to the far edges. The backside on this one is as sweet as the front, displaying a much more mature galaxy with clearly defined star structure in place. If you like or looove space, then this NEEEDS to be in your collection!
