SkyServer Challenges are designed to stretch your thinking with difficult questions and long-term projects. These challenges are even more extensive that the Research Challenges at the end of the other Projects.
Many of these challenges are ideas that SDSS astronomers thought of, but haven't had the chance to work through yet. So when you finish a challenge, your results might be used by SDSS astronomers to advance their research. If you want to make a genuine, original contribution to the future of astronomy, this is the place to do it!
