Stellar Classification Online Public Exploration needs the help of citizen scientists to observe and classify stars never before classified. The goal is to mine data from photographic images of star spectra, which result from light absorption in the outer surface of a star. Star spectra are made available online where citizen scientists can compare them to stars with known spectra. Don't wait--be the first to classify one of hundreds of thousands of stars that have never been seen before!
