A pulsar (pulsating star, on the model of quasar) [1] is a highly magnetized rotating neutron star that emits beams of electromagnetic radiation out of its magnetic poles. [2]

Jan 24, 2023 · Pulsars are 'cosmic lighthouses' that when seen from Earth appear to be flickering stars, but actually consist of exotic stellar remnants called neutron stars.

Jul 15, 2022 · Bottom line: A pulsar is a neutron star with its poles aimed toward Earth so that we can see pulses of light resulting from the star’s strong emission when it’s rapidly spinning.

Feb 5, 2025 · Pulsars are rapidly spinning neutron stars, extremely dense stars composed almost entirely of neutrons and having a diameter of only 20 km (12 miles) or less. Pulsar masses range between 1.18 and 1.97 times that of the Sun, but most …

PSR B1919+21 is a pulsar with a period of 1.3373 seconds [4] and a pulse width of 0.04 seconds. Discovered by Jocelyn Bell Burnell on 28 November 1967, it is the first discovered radio pulsar. [5]

From the Earth, a pulsar looks like a star that has a pulse, a rapid beat picked up only by radio telescopes. Discoverers Jocelyn Bell and Antony Hewish noticed that these beats were so regular that they seemed manmade.

Everything you need to know about pulsars and how these spinning neutron stars were discovered.

Aug 17, 2020 · A Pulsar is a core of a star that has collapsed into a neutron star. Pulsars spin very rapidly and have strong magnetic fields. A Pulsars powerful magnetic field produces a thin yet strong beam of electromagnetic radiation that is shot into space.

A neutron star is the remaining core of a massive star, once it has exploded. They come in different types, including fast-spinning pulsars and and strongly magnetic magnetars. Millions of neutron stars populate our galaxy, the Milky Way.

Sep 23, 2024 · Pulsars are rapidly rotating neutron stars that blast out pulses of radiation at regular intervals ranging from seconds to milliseconds.
