Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. For the remote Uranian system of moons, namesakes from Shakespearean works have been chosen. Thus Oberon , king of the mid-summer night fairies, is also Uranus' most distant and second largest moon and Hamlet is a tragically large and princely crater on its surface . Hamlet is the large dark crater to the right of center. In 1986, Voyager 2 flew through the Uranian system - so far it has been the only spacecraft to do so.
