Ever fancied yourself as a bit of a galaxy hunter? Ever looked up at the stars and wondered if you are alone out there? Well, never mind the second question, but if you want to help classify over a million galaxies, then Galaxy Zoo could probably use your help.
They have taken photo’s of around a million galaxies (each one contains billions and billions of stars like our own sun…do the maths, it’s not hard to realize there is going to be at least one other ‘Earth’ out there capable of supporting life) and need help classifying them all.
You have to take a short tutorial explaining the different types of galaxies (Eliptical or Spiral) and then have to take a nerve racking test to find out if your galaxy hunting skills are good enough for what they need. If you pass then you are allowed to start classifying real galaxies.
The whole concept of letting people around the world help out with scientific studies is growing in popularity. Classifying the galaxies has been difficult to do with computers because they are not adept at spotting patterns, and getting a few people to so the classification would take time and resources. By letting hundreds, thousands, maybe tens of thousands of people around the world help out they can complete their study in months rather than years.
