Astronomers have confirmed the existence of a new kind of star that generates intense bursts of radiation and the strongest magnetic forces ever seen in the universe, researchers said Friday.

The magnetic forces in a "magnetar" are so intense they create violent seismic waves called "starquakes," which release more radiation in a fraction of a second than the sun releases in a year.The magnetar, named SGR 1806-20, is located about 40,000 light years from Earth, researchers from NASA's Marshall Space Flight Center in Huntsville, Alabama said in the journal Nature.
