Ah, the moon. Or the Moon. It depends upon to which school of English grammar you suscribe to. Either way, it is Earth's closest celestial neighbor, yet it is very different from Earth in many ways. Most noticably, it displays a tale of solar system astroidal bombardment since its formation nearly 4.5 billion years ago. The many craters and dark-filled lava basins (mare, meaning "sea") present probably the most oft-photographed celestial object. It is the first celestial object that I photographed, and I have many images of it, the best of which are found on this page.
