The Curiosity rover, which is designed to explore Mars, has found an ancient oasis on Mars. Researchers working with the Curiosity rover have found salt-enriched…
The pulsar is a fast-spinning neutron star with a strong magnetic field. This combination powers a lighthouse-like beam of energy, which astronomers can easily locate if the beam happens to sweep toward Earth. Australian astronomers have found the record failed in the motion of the pulsar, that is unexplainable a sharp change of speed of rotation.Record holder was the pulsar J1718-3718, discovered in 2004. Numerical characteristics of the event, which is characterized by the ratio of rotation speed to the speed of rotation prior until the crash, was 33,25 x10-6. The previous record, set by the pulsar B2334 +61, was 20,5 x10-6.
These changes are associated with enormous energy of consumption because of the large masses (several solar with an average diameter of 12 kilometers) and the enormous speeds of rotation (for example, period of revolution J1718-3718 is 3.378 seconds).The observed failure has another unusual feature. After such an event rate of the rotation of neutron star comes back to normal, but for J1718-3718 normalization is not observed already for 700 days. Moreover, according to scientists, the magnetic axis and the axis of rotation of the neutron star at the present time “costs”. Scientists can’t yet explain the processes occurring inside stars.
