If you're already running Folding@Home and SETI@Home, I have another way for you to participate in the global, scientific progress. You can help spot super novae!
Apparently, super novae are problematic things to catch, because even though they happen frequently enough, they only last a short time. And every night there are thousands of photographs that people must sift through by hand and analyze personally to tell whether what they're seeing is a true super novae.
C'mon. All the cool kids are doing it.
