宇宙中的燈塔-中子星(引自NRAO美國國家電波天文台)

Did You Know?

Jocelyn Bell and Antony Hewish accidentally discovered the extraordinary celestial objects know as “pulsars” in 1967 while they were searching for twinkling sources of radio radiation. The explanation for the rapid radio pulses Bell and Hewish observed proved the existence of neutron stars, incredibly dense remains of massive collapsed stars. Neutron stars were predicted in the 1930s by several visionary astronomers and physicists.
