7 years ago, Kevin Schawinski, a young astronomy researcher at Oxford, met up with his colleague Chris Lintott at a local pub. Schawinski had started the tedious task of looking through images of a million galaxies that he needed to classify. He’d just spent the whole week doing this and had completed just 50-thousand of them. He told his friend Chris he wasn’t looking forward to spending months going through the rest. The solution they came up with was Galaxy Zoo, a way for anyone to go online and work on real science.
