Rare magnetic star discovered

Astronomers led by a scientist from the University of Amsterdam (UvA) have a 'magnetar' discovered. This made the European Space Agency ESA known. This rare type of star has the largest magnetic power of all objects in the universe.
So far there are only 15 known magnetars. The latter was discovered ten years ago, astronomers said Nanda Rea of the University of Amsterdam, which the 'new magnetar' discovered. The star explodes and thousands of years ago is about 15,000 light years from Earth.
The magnetic field of a magnetar is 10,000 million times as strong as that of the earth. His great strength is noticeable even on the earth.
Thus causing the eruptions of the magnetars, if they reach the earth, sometimes interfere with the telephone network. "It depends on the size of the eruptions on how large that failures can be. Sometimes it is a millisecond, sometimes hundreds of seconds," says Rea. (belga / SPS)
