Galaxy Zoo – the project which harnesses the power of the Internet – and your brain – to classify a million galaxies.
This site is interesting, just sign up and pass the simple test and you will be contributing to scientific research. There is no any software on this world that can scan and tell which type of the galaxy is. The only thing which can do the analyses better is the human mind.
I’m part of this, and can tell its interesting not only helping but you will also learn the types of Galaxy and how to describe them when using your own telescope.
