BOINC bags a pulsar via Einstein@Home distributed computing

Hot on the heels of the FoldIt paper in Nature, Science is publishing a bit of citizen science of its own. The results come from the Einstein@Home distributed computing project, which is one of the many projects now using the BOINC platform to perform distributed computing projects via a cross-platform screensaver. Although Einstein@Home users generally spend their time searching for gravity waves, a side project under the same umbrella has enabled a home computer to spot a rare pulsar in radio observatory data.

Pulsars are rapidly spinning neutron stars that have formed during a supernovae. Their rapid rotation causes the emission from the poles to sweep across the line-of-sight to the Earth, creating a periodic flash. Initially, most pulsars are energetic, rotating rapidly and emitting radiation in the X-ray region. But, over time, they spin down, and many only emit at radio frequencies.
