Have you ever wondered who decides what type of Galaxies we have in our universe, or who decides the different types of terrain on Mars?
Well you now have the chance to decide for yourselves, below are two links that put you in the driving seat of choosing whether a Galaxy is spiral or elliptical and even what direction it rotates, or even chose what a part of the Martian terrain is like.
Galaxy Zoo is a new on-line project to classify a million galaxies in our universe, after registering you can start deciding for yourself what type of galaxy your monitor is showing you (It is a good Idea to start at the tutorial though)
HiRISE Clickworkers Calls on volunteers to look through images of theMartian terrain and deciding the different types of features shown in the images, you can even Help find new places on Mars for HiRISE to take pictures using the Mars Global Surveyor (MOC) images"(there is no need toregister either)
