This artist’s concept shows a pulsar, which is like a lighthouse, as its light appears in regular pulses as it rotates. Pulsars are dense remnants of exploded stars, and are part of a class of objects called neutron stars. Credit: NASA/JPL-Caltech
These pulsars – neutron stars that rotate and emit lighthouse-like beams of radio waves that rapidly sweep through space – were used to identify mysterious hidden masses. This image shows an artist’s impression of a neutron star, surrounded by its strong magnetic field . It emits a narrow beam of radio waves 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.
Professor LoSecco said: “We take advantage of the fact that the Earth is moving, the Sun is moving, the pulsar is moving, and even the dark matter is moving.
