Galaxy Zoo: Hubble

I've talked about Galaxy Zoo before a couple of times. It's a citizen science project to classify galaxies from automated sky surveys by type and shape. After not doing anything on the project in 18 months, I'm back. I've classified 135 'galaxies' today... including about actual galaxies, plus a few stars and a satellite trail.

The new project uses galaxies from the background of several Hubble Space Telescope images. Many are proto-galaxies from the beginning of the universe, too young to have formed into round spirals or ellipses. They just look like - like bluish lumps. Some 10 billion years old.
