The Mount Wilson Observatory has been responsible for some of the most important events in the history of modern science including Edwin Hubble's discovery that there were galaxies outside of our own, and Milton Humason's discovery that the universe is expanding. For the last hundred years the astronomers at Mount Wilson have been making photographic records of their observations. Some of these, like images of the Sun and the Moon, are recognizable to us as pictures. Others manifest only as information. While this latter group may seem to us decipherable only to scientists with specialized knowledge, they too, are a way of representing the world through the medium of photography. In celebration of the 150th birthday of George Ellery Hale (the founder of Mount Wilson Observatory) a series of prints were made from the original glass plate negatives.
