Pulsars Have Crunchy Crust and Supersmooth Interiors A Study Suggests
Why do pulsars, one of the universe's most reliable clocks, occasionally speed up? A new theory suggests there's a superfluid at the heart of this mystery.

Neutron Stars and Pulsars Introduction - Imagine the Universe
A neutron star is about 20 km in diameter and has the mass of about 1.4 times that of our Sun. This means that a neutron star is so dense that on Earth, one teaspoonful would weigh a billion tons! Because of its small size and high density, a neutron star possesses a surface gravitational field about 2 x 1011 times that of Earth. Neutron stars can also have magnetic fields a million times stronger than the strongest magnetic fields produced on Earth.

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.

What is a Pulsar? - Universe Today
They are what is known as the "lighthouses" of the universe - rotating neutron stars that emit a focused beam of electromagnetic radiation.

Pulsar - Wikipedia, the Free Encyclopedia
A pulsar is a highly magnetized, rotating neutron star that emits a beam of electromagnetic radiation. This radiation can be observed only when the beam of emission is pointing toward Earth (much the way a lighthouse can be seen only when the light is pointed in the direction of an observer), and is responsible for the pulsed appearance of emission.
