Artist Impression of a Pulsar (image) Max-Planck-Gesellschaft Share Print E-Mail Caption Einstein@Home searches for unknown neutron stars through their pulsed radio emission. This image shows an artist's impression of a neutron star, surrounded by its strong magnetic field (blue). It emits a narrow beam of radio waves (magenta) above its magnetic poles. When the star's rotation sweeps these beams over the Earth, the neutron star can be detected as a radio pulsar.
