Superlight impulses of pulsars will tell about hydrogen.



Within the limits of work researchers observed for PSR B1937+21. This object settles down in constellation of Lisichki on distance about 13 thousand light years from the Earth and makes 642 complete revolutions round own axis in a second. Astrophysics have collected the data about supervision over a pulsar for three days, using a radio telescope in Puerto Rico.

As a result scientists have established that the part of impulses arrives to the observer before an estimated time that specifies in an abnormal dispersion. This phenomenon at which the indicator of refraction of environment decreases with increase in frequency of electromagnetic waves. As the usual impulse is made of the whole set of waves, its average speed can be above a velocity of light. As the part of waves lags behind, the given phenomenon does not contradict the relativity theory: no superfast carrying over of the information occurs.

According to scientists, the reason of an abnormal dispersion in their case is the resonance of neutral hydrogen in clouds which the pulsar beam crosses on a way to the Earth. Scientists notice that new results will help researchers with hydrogen studying, however as is concrete, in this work is not specified.

More recently astronomers managed to define, whence has occurred fastest of known pulsars - object PSR B2224+65. This neutron star moves with a speed about 1500 kilometres per second in relation to the observer on the Earth. The shock wave created by object, is responsible for formation of a fog the Guitar.
