Einstein@Home project uses data from Arecibo, the world's largest and most sensitive radio telescope
Aug 12, 2010. Idle computers are the astronomers' playground: Three citizen scientists--an American couple and a German--have discovered a new radio pulsar hidden in data gathered by the Arecibo Observatory. This is the first deep-space discovery by Einstein@Home, which uses donated time from the home and office computers of 250,000 volunteers from 192 different countries. This is the first genuine astronomical discovery by a public volunteer distributed computing project. The details of their discovery and the process of getting there are revealed in a paper published in the Aug. 12 edition of Science Express.
The new pulsar--called PSR J2007+2722--is a neutron star that rotates 41 times per second. It is in the Milky Way, approximately 17,000 light years from Earth in the constellation Vulpecula. Unlike most pulsars that spin as quickly and steadily, PSR J2007+2722 sits alone in space, and has no orbiting companion star. Astronomers consider it especially interesting since it is likely a recycled pulsar that lost its companion. However they cannot rule out that it may be a young pulsar born with an lower-than-usual magnetic field.
