Einstein@Home is a program that uses your computer's idle time to search for spinning neutron stars (also called pulsars) using data from the LIGO gravitational wave detector. It also searches for radio pulsars in binary systems, using data from the Arecibo Observatory in Puerto Rico. Einstein@Home is a World Year of Physics 2005 and an International Year of Astronomy 2009 project supported by the American Physical Society (APS) and by a number of international organizations.

If you would like to take part, please follow the "Join Einstein@Home" instructions to the left. Einstein@Home is available for Windows, Linux and Macintosh OS X computers.

Einstein@Home is now carrying out a search of data from LIGO's first science run at design sensitivity (S5). The current analysis (S5R5/6) uses 5280 hours of data from the later (and most sensitive) part of S5. For more information, please see the "Science information" section on the left of this page.

News items

February 9, 2010
The Einstein@Home project was not sending out any emails for the last few days due to misconfiguration. The problem has been fixed and we apologize for the inconvenience.

February 1, 2010
Our database is currently pretty slow, due to a large number of ABP2 results. We are taking measures to keep the project running, but with a few restrictions: The scheduler (task sending and reporting) is disabled part of the time (clients will see a 'temporarily down for maintenance' message). The server status page has been disabled. We'll also reduce the time results are kept in the database. Hopefully we will be able to return to normal operation in a few days.

January 15, 2010
The (re-)discovery page has been updated to include the latest observations made by the search for binary pulsars in Arecibo radio data. In total there are now 53 re-observations of 34 different radio pulsars, including 10 re-observations of 3 different milli-second pulsars. Thanks to all participating volunteers!

January 6, 2010
The Arecibo Binary Pulsar search is undergoing a major transition. We expect clients to not get ABP1 tasks for a while, then, if all goes well, tasks for a new application called ABP2. Read more about this here.

December 30, 2009
You may have noticed that the E@H server has been a bit slow over the last 12 hours. There was a bad entry in the database that was causing problems for the transitioner. The project should be more reponsive now.
