Dear all,
Today's Object of the Day is not an object, but a request for some. Zookeeper Rob is looking for an "Object of the Day" for a Zoo Advent Calendar, which should be interesting (open up this pocket of space and - oops, a black hole!

). Want to help?
From now until Monday, please post your favourite galaxy, either from Hubble Zoo or from SDSS. On Monday we will have a poll, closing on Tuesday night.
Please don't post millions of galaxies as it will take me ages to write the poll - I suggest a maximum of three per person!

Here are mine:
587728879266299939
587729388225363990. . . and, of course:
587726033843585149 - well, what did you expect?

What are yours?
