Astrophysics Netherlands Institute for Radio Astronomy and the University of Amsterdam reported today that the double pulsar J1906, for which they were followed for 10 years, suddenly disappeared. J1906 changed the axis of its orbit.
It is reported that the rotating part of the binary pulsar change the inclination of the axis of its orbit so that its rays pass by these lands, so the pulsar is no longer visible. According to the calculations of astrophysicists, the pulsar may again appear in a field of view of scientists only after 160 years in 2175.
It should be noted that the pulsar J1906 was discovered in 2004 by researchers Arecibo Observatory in Puerto Rico. The star was born about 100 thousand years ago in the explosion. The space object is located at a distance of 25,000 light-years from Earth in the star cluster Terzian 5. Weight pulsar is about the same as that of the Sun, with a diameter of 10-20 kilometers.
The first pulsar was discovered in June 1967, Jocelyn Bell, a graduate student Anthony Hewish, the meridian radiotelescope Mallardskoy Radio Astronomy Observatory, University of Cambridge at a wavelength of 3.5 m (85.7 MHz) . During this outstanding result Hewish received the 1974 Nobel Prize. The modern name of the pulsar – PSR B1919 + 21 and PSR J1921 + 2153.
