Hoag's Object
(Preview)
Galaxies come in a variety of shapes, but most fit into one of just a few categories - simple spheroids or ellipses, flattened discs, elegant spirals like the Milky Way or irregularly shaped blobs. But Hoag's object is so bizarre that when astronomer Arthur Hoag first spotted it in 1950, he wasn't eve...
