To understand how galaxies have formed, astronomers need your help to classify them according to their shapes. If you're quick, you may even be the first person to see the galaxies you're asked to classify. Images come from telescopes including Hubble and the Sloan Digital Sky Survey.

This app caches several subjects locally so you can classify even while offline and have the classifications automatically uploaded later.

* The sequence of questions is determined by the Galaxy Zoo project and is consistent with the web UI.

What's New in Version 1.15

5/5 stars

Galaxy zoo

I would like to be able to save the pictures on my iPod because there are some really cool ones. It's a great app though!

5/5 stars

Looks good!

I like it, but have you considered adding this key-value combo to the plist? UIStatusBarStyle : UIStatusBarStyleBlackOpaque The Default UIStatusBar seems to stick out is my only complaint! :o)

5/5 stars

Galaxy Zoo rocks!

Wow, the app really is better than the website!

If you haven't 'zooed before, you will need to get familiar with how to classify galaxies on the website. But once you have the hang of it, the app is easier, faster, and way more convenient. So easy and fast that it now rivals just about any game on my iPod for fun factor.
