Einstein@Home is one of the largest distributed volunteer computing projects in the world and has more than 330,000 participants.
Einstein@Home uses idle computing time donated by volunteers all around the world. The aggregated computing power equals roughly one PetaFlop/s and is used to search for weak astrophysical signals from spinning neutron stars (also called pulsars). Einstein@Home analyzes data from the LIGO gravitational-wave detectors, the Arecibo and Parkes radio telescopes, and the Fermi gamma-ray satellite.
Einstein@Home volunteers have already discovered almost fifty new neutron stars, and we hope to find many more in the future. Our long-term goal is to make the first direct detections of gravitational-wave emission from spinning neutron stars.
Gravitational waves were predicted by Albert Einstein almost a century ago and have been directly detected for the first time on 14 September 2015. These first observations have opened up a new window on the universe, and ushered in a new era in astronomy.
