November 28, 2007, astronomers using the Chandra X-ray Observatory (Chandra), discovered one of the fastest stars ever found a man in space. Star, which has the official name of RX J0822-4300 was immediately given the nickname of "cosmic cannonball" because of its ultra-fast transfer across the expanses of space.

RX J0822-4300 - a neutron star, a supernova explosion born of the constellation Puppis A nearly 3700 years ago. Using the Chandra can be seen as a neutron star is moving away from the epicenter of the explosion at a huge rate of 3 million miles per hour. At this speed, RX J0822-4300 will go beyond the Milky Way, just some few million years.

Astronomers are already familiar with such speed the stars being ejected from the Milky Way, but few stars have such a tremendous pace as this neutron star.

In spite of this high rate of displacement, see the motion of the star is not so easy. During the five years of the movement, the star has moved a distance approximately equal to the size of the numbers on the coin, remote from the observer is almost 100 meters. Surprisingly, the Chandra observatory has such power that it is able to notice even a little-noticed change in the pattern of the sky.

Astronomers are not the first time a star moving at that speed. Such Hyperspeed stars, escaping beyond the Milky Way, and were detected before, but their speed is rarely more than a million miles per hour. The main difference between RX J0822-4300 from the likes of stars - a source of acceleration. It is believed that ultra-Stars are accelerated by the interaction of supermassive black holes at the center of the galaxy, serving a kind of giant gravitational slingshots, catapulting stars in space. But the observed neutron star, in contrast to similar stars, has received accelerated by the explosion of a supernova. The data obtained suggest that the explosion was uneven, resulting in a neutron star flew in one direction and the debris from the explosion - in another.

And yet, the dizzying speed of the neutron star in the constellation of Puppis A is not so easy to explain, even using the most modern methods of modeling of supernova explosions. Riddle lies in the very nature of the formation of this kind of explosions that have such power and energy that they are able to give a crazy acceleration of objects within their epicenter.
