To date, 55 radio pulsars have been discovered by @einsteinathome and its volunteers, and there may be many more to come.

“Einstein@Home has found radio pulsars in archival data that have been thoroughly analyzed many times before,” says Colin Clark, group leader of the Pulsars group at the @mpi_grav in Hannover, Germany. “This is why we expect to find many more exciting radio pulsars with Einstein@Home in the future.”
