A celestial object, thought to be a rapidly rotating neutron star, that emits regular pulses of radio waves and other electromagnetic radiation at rates of up to one thousand pulses per second.‘Black holes, the cosmic microwave background, pulsars, neutron stars, gravitational lenses, gravity waves - these are just a few of the phenomena that would make no sense without general relativity.’
- ‘These emanations come from rapidly spinning neutron stars called pulsars - rotating beacons that periodically send energy in the direction of the earth.’
- ‘The object is being stimulated by jets from a rapidly spinning (about thirty times a second) neutron star called a pulsar.’
- ‘The Universe has its own heavenly sounds, such as pulsars, planetary magnetospheres and solar winds.’
- ‘I read up on interstellar objects and astrophysics and studied quasars, pulsars and supernovas, but my main focus was black holes.’
From puls(ating st)ar, on the pattern of quasar.
