Galaxy Zoo

I have spent several hours during the past three days at a web site I just found.

The folks over at Galaxy Zoo are looking for volunteers to classify millions of galaxies:

Dear Galaxy Zoo users,

Thanks for making Galaxy Zoo such a success!

With your help, we’ve been able to collect millions of classifications, with which to do science faster than we ever thought possible. We are currently preparing the first science papers for submission to peer-reviewed journals and we will keep you posted on the progress of the papers on the BLOG and the FORUM. From now on, if you classify galaxies on the ANALYSIS page, your classifications will continue to be recorded and will be part of the public release, but it won’t be part of the first round of papers. Don’t be alarmed if the galaxies are odd, this is part of the process of checking our results.

But we still need you! As part of our follow-up work, we need volunteers to review our set of possible merging galaxies. If you’re already familiar with basic Galaxy Zoo analysis, click here to read the instructions and click here to take part. Galaxy Zoo 2 will go live in the near future featuring a much more detailed classification system, while further off we plan GalaxyZoo 3 with lots of exciting new data. We’ll notify all of you via the newsletter when we’re able to start these two new endeavours.

Once you register and log in, they give you a tutorial on classification, and then you take a test. Fifteen galactic images. Off to the side is a handy chart. Click on one of six images that correspond to your classification.

After that, its off to the analysis page.

Here is one presented to me during a recent run:


Its a routine clockwise spiral galaxy.

Now what is this?


Is it a merger? Is it a spiral, an elliptical?

So far, I have tagged 225 images.
