For the last three years the Royal Observatory Greenwich, in association with Sky at Night Magazine, has sponsored the Astronomy Photographer of the Year competition. 2012 saw a record number of entries from all over the world. With the results to be announced in just a few hours, it would be well worth your while to check out some of the really remarkable entries in the competition. You can see a few at the Guardian website, and others at this Flickr page. Past winners can be seen at the Royal Observatory Greenwich website. Below are a couple of my favorites.
