The life of a high mass star is a short one, it ends in an explosion called a supernova. All that remains of the once brilliant star is the core, a neutron star. The path of the neutron star branches, it can either become a black hole, or something called a pulsar. For it to become a pulsar it has to take on a rapid spin, the fastest-spinning  neutron star that has ever found is 20 miles in diameter and very dense. It spun faster than even the blades of a blender. The star then spews out a massive discharge of radiation along the lines of its magnetic field, called a jet. A jet can be anything that emits a beam of matter from itself like water from a hose. They can occur in many astrophysical events like pulsars. This makes it an official pulsar, of which there are estimated to be about 200,000 of.

The first pulsar ever discovered was discovered in the fall of 1967, when a post-graduate named Jocelyn Bell was examining many charts of radio measurements of the sky. The data was acquired with a massive radio telescope that was located at the University of Cambridge. She found that what she had seen earlier that summer, and thought to be a distortion in the chart, was actually a group of tightly packed radio pulses.

Antony Hewish, Jocelyn’s adviser, who had designed the telescope, thought that the strange radio pulses were man made interference. However, after more research it became clear that the radio pulses were originating from a fixed place in space, somewhere in the constellation of Vulpecula the Fox. They thought that it could’ve been a message from an alien race. They even named the strange radio signal LGM-1, standing for Little Green Men.

But, more ‘pulsating stars’ were found in 1968, called pulsars for short and it soon became very clear that Jocelyn had found a new type of celestial body. Then, astrophysicist Fred Hoyle, began to think that they might be the leftovers of supernovas. Later, other scientists confirmed that these pulsars had to be rapidly spinning neutron stars. That same year the discovery of a new pulsar the  Crab pulsar, was made in the center of the remnants of a supernova. Confirming that they were birthed from supernovas.

In the years to follow, pulsars were found to be located in some binary systems, this helped to support the theory of general relativity that Einstein proposed. And in 1982, a pulsar that spun every 1.6 microseconds was discovered. Also, the very first extrasolar planets (a planet that doesn’t orbit our sun) that were discovered were orbiting a pulsar. However, none of them had a great possibility for life.

Other pulsars are just as brilliant as the Vela pulsar and have some interesting properties. A pulsar has the most energy and speed when it is first formed, as it loses that during its life and within 10-100 million years the jet will stop and it will become silent. Pulsars while active can be used as timers because of their consistency in spinning. Some pulsars even rival atomic clocks in their accuracy.

*The Vela pulsar is about 1000 light years from Earth
*When a pulsar first forms, it has the most energy and fastest rotation speed. As it releases electromagnetic power through its jets, it gradually slows down.

*When they are active, they spin with such regularity that they’re used as timers by scientist.

Jets are beams of matter ejected from some astronomical objects like water from a hose. They occur in a number of astrophysical situations.

This pulsar lies near the centre of the Vela supernova remnant, which is the debris of the explosion of a massive star about 10,000 years ago. The pulsar is the collapsed core of this star, rotating with a period of 89 milliseconds or about 11 times a second.

Pulsars form from the supernova of massive stars, that then turn into neutron stars and take on a fast spin.

http://www.astropage.eu/index_news.php?id=938 Neues Chandra-Video zeigt einen Neutronenstern in Aktion The Chandra data set contains 7 images obtained between June and September 2010, and suggests that the pulsar may be slowly wobbling, or precessing, as it spins. The shape and the motion of the Vela jet look strikingly like a rotating helix, a shape that is naturally explained by precession, as shown in this animation.
