Einstein@home is an international project launched in 2005, which tries to prove the predicted gravitational waves by Albert Einstein.

For this purpose, 3 detectors in Hanover (Germany Google Maps), Livingston (USA, Google Maps), Hanford (USA, Google Maps) and Pisa (Italy, Google Maps) measure by laser the length of 2 orthogonally arranged vacuum tubes, which are up to 4 km long. Upon impact of a gravitational wave (for example, from a supernova explosion), the length is supposed to change. The detectors are able to detect changes on the order of a thousandth of a proton diameter (about 10 ^-18 m).

Since March 2009, participants can also participate in the analysis of data from the Arecibo radio telescope in Puerto Rico, contributing directly to the discovery of unknown radio pulsars. The Arecibo Observatory is the largest single-reflector radio telescope in the world. It examines pulsars, galaxies, objects in our solar system and the atmosphere of the earth. In August 2010, a first hitherto undiscovered pulsar was found in this search, the discovery of another, binary pulsar was announced on March 1, 2011.

Since August 2011 another project has been started. This searches for gamma pulsars, including the first millisecond pulsar, which shows only in the gamma region, in the data of the Fermi satellites.
