The Chandra X-ray observatory in space, NASA has allowed the observation of a runaway pulsar, which means that it belongs to the category of stars that move at speeds abnormally high compared to what surrounds them. This neutron star, known as IGR J11014-6103, is moving at a speed yet to be measured exactly between 4 and 8 million km/h (between 2.5 and 5 mph). Another extraordinary feature of this pulsar is the tail created by a jet of high-energy particles, which extends for some 37 light years.
