New science results from Galaxy Zoo

Dear Galaxy Zoo

It's been an exciting few weeks at Galaxy Zoo, with two particularly cherished scientific results being accepted by the journals, thanks to all the hard work you've provided via GalaxyZoo.org.

The first is a study of mysteriously bulgeless galaxies. These spirals, which lack the normal 'bulge' of stars you see at the centre of most such galaxies, including the Milky Way, are guaranteed (we
think!) never to have had a merger. They can uniquely tell us about the effect dramatic mergers have on galaxies unfortunate enough to endure them - the ones highlighted in this recent paper have surprisingly large black holes, which must have grown in this unique merger free environment.

Bulgeless galaxies are a new departure for us, but the other paper is a study of some of our oldest finds. Bill Keel and team - including a whole host of Galaxy Zoo users - are proud to publish the official Galaxy Zoo catalogue of 1990 overlapping galaxy pairs. Before we started, only 20 of these unique systems were known so this is a huge advance. Congratulations to all, particularly the dedicated denizens of the forums who tracked them all down.

If you haven't had enough galaxies, then we'd also like to invite you to take a close look at the large system nearest to home.
Andromedaproject.org is the latest Zooniverse project, and it aims to create a unique catalogue of star clusters in the Andromeda Galaxy.
There are also a few more distant galaxies lurking in these stunning Hubble Space Telescope images, waiting to be discovered. Please do go and try it out.

Thanks again for all your help

Chris & the Galaxy Zoo team.

P.S. We're currently testing some new Zooniverse education projects, if you are a teacher who is currently using Galaxy Zoo or any other Zooniverse project in the classroom then please email [email protected] with the subject 'Beta testing'.
