What are pulsars? | Space
2023年1月24日 · Pulsars are rapidly rotating neutron stars that blast out pulses of radiation at regular intervals ranging from seconds to milliseconds. Pulsars have strong magnetic...
Pulsar - Wikipedia
Pulsar maps have been included on the two Pioneer plaques as well as the Voyager Golden Record. They show the position of the Sun, relative to 14 pulsars, which are identified by the unique timing of their electromagnetic pulses, so that Earth's position both in space and time can be calculated by potential extraterrestrial intelligence.

What’s a pulsar? Why does it pulse? - EarthSky
2022年7月15日 · There’s a rapidly spinning neutron star at the center of the nebula, known as a pulsar. It’s the rightmost of the 2 stars near the center of the image. The bluish light is radiation emitted by ...
NASA | What is a Pulsar? - YouTube
A pulsar is a neutron star that emits beams of radiation that sweep through Earth's line of sight. Like a black hole, it is an endpoint to stellar evolution....
What are pulsars? - Live Science
2022年5月24日 · A pulsar is a special kind of neutron star, which is the ultra-dense leftover core of a massive star. Pulsars emit beams of radiation that sweep out in circles as the pulsar spins. When those...
An Introduction to Pulsars - Australia Telescope National Facility
This webpage has been designed to give you an understanding of pulsar astronomy. We start by describing how astronomers discover and subsequently observe pulsars. We continue with a section on the theory of pulsars where we explain why pulsars are thought to be neutron stars (the collapsed core of a star that underwent a supernova explosion).
Pulsar | Cosmic Object, Neutron Star, Radio Wave Emission
5 天之前 · 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 …
Pulsars Astronomy – National Radio Astronomy Observatory
A really massive object like a planet or a star curves space around itself. Light traveling along through space will follow that curve. In this artist's drawing, the pulses from a pulsar are distorted as the radio waves pass through the gravity pull of a massive object.
What Is a Pulsar? | History, Types & Fascinating Traits
A pulsar is like a cosmic lighthouse in space. It’s a type of rotating neutron star, which is incredibly dense and formed from the remnants of a massive star’s explosion. As the pulsar spins, it emits beams of radiation from its magnetic poles.
