Pulsars emit precise radio beams like cosmic lighthouses

Rapidly spinning neutron stars pulse with regular precision across space

Pulsars are highly magnetized neutron stars that emit beams of electromagnetic radiation from their magnetic poles. As the neutron star rotates, these beams sweep across space like a lighthouse beacon, producing periodic radio pulses with timing accuracy rivaling atomic clocks.
