Activity 1: QuizWho discovered the first pulsar?
What was the significance of the discovery of the pulsars in the Crab Nebula and the Vela Supernova Remnant?
Pulsars were discovered in places where neutron stars were predicted to existAstronomers realized that pulsars emitted all types of electromagnetic radiation, from gamma ray to radioThis event marked the discovery of the first millisecond pulsarsAstronomers discovered that pulsars could be optically viewed, as opposed to just measuring radio waves
When radio astronomers view pulsars, they are really viewing
Beams of radiation from a neutron star that are pointed at EarthThe spin axis of a neutron starThe intense gravitational field of a neutron starThe magnetic field of a neutron star
Which of the following is NOT a characteristic of

They are relatively old.They are smaller than normal pulsars.They spin more rapidly than normal pulsars.They make very accurate timekeepers.
discovered.
