Scientists Capture , Radio Signals , From Long-Dormant Star.<br/>'The Independent' reports that scientists have <br/>been puzzled after receiving unprecedented <br/>radio signals from a previously dormant star.<br/>The star, named XTE J1810-197, is a magnetar. .<br/>Magnetars are a type of neutron star and are <br/>the most powerful magnets in the universe.<br/>XTE J1810-197 is the nearest known magnetar <br/>to Earth, about 8,000 light years away.<br/>Now, scientists have received radio <br/>pulses from the dormant star that <br/>do not fit previous expectations.<br/>Unlike the radio signals we’ve <br/>seen from other magnetars, <br/>this one is emitting enormous <br/>amounts of rapidly changing <br/>circular polarisation. We had never <br/>seen anything like this before, Marcus Lower, Postdoctoral fellow <br/>at Australia’s national science agency, <br/>CSIRO, via 'The Independent'.<br/>Scientists discovered that the new pulses are emitting <br/>a type of spiraling light that is different from the<br/>polarized light emitted by most other magnetars.<br/>In 2003, XTE J1810-197 became <br/>the first known magnetar to <br/>produce a radio signal.<br/>After being discovered, the magnetar <br/>then went silent for over a decade. .<br/>The team that discovered it said that <br/>the findings could change our <br/>understanding of intense magnetic fields.<br/>The signals emitted from <br/>this magnetar imply that <br/>interactions at the surface <br/>of the star are more complex than <br/>previous theoretical explanations, Manisha Caleb, University of Sydney, <br/>a co-author on the study, via 'The Independent'.<br/>The team's findings were published <br/>in the journal 'Nature Astronomy.'
