It seems that people like galaxies — a lot. So much so that the Galaxy Zoo project is off to a flying start. According to a press release this week, since mid-July 85,000 people have signed up to pore over images of galaxies from the Sloan Digital Sky Survey to help classify more than one million star systems.
Unlike other "@home" computing projects — looking for aliens and looking for cures for disease — that just require your computer to run software in the background or while the CPU's idle, Galaxy Zoo needs brainpower. Participants have to make a human judgment to classify the galaxies.
If you don't want to miss out, take the tutorial of galaxy morphology (the scientific way of saying "shape and structure") and join in.
