Take the mass of half a million worldly concern and press it down to the size of it of Manhattan . If you have look at care and survived the muscularity release from this mental process , then well done ! You ’ve got yourself a neutron star , one of the heavy objects in the universe .
Under certain conditions neutron principal are not just the small and dumb adept out there , they can also be " magnetars " – the strongest magnets in the universe . Now , for the first time , astronomers have spotted one of these magnetars surrounded by a wind nebula .
The physical object is called Swift J1834.9 - 0846 , or J1834.9 for shortsighted , and astronomers call up it ’s associated with the W14 supernova remnant . Neutron stars contour in powerful supernova explosions , which also create tumid cloud of material . These are pushed and easy wear away by the energetic luminousness and particles from the genius , and so they are nicknamed wind nebulae .
" Right now , we do n’t recognize how J1834.9 develop and continue to uphold a wind nebula , which until now was a structure only seen around young pulsar , " say lead researcher George Younes , a postdoctoral researcher at George Washington University in Washington , in astatement .
Wind nebulae , like the renowned crab nebula , shine from the streams of particles emitted from the neutron mavin , which can gyrate hundreds of times per second . Some of this rotational vigor is spend to get light and the hefty current of particles .
" If the unconscious process here is standardized , then about 10 pct of the magnetar ’s rotational energy red ink is powering the nebula ’s glow , which would be the highest efficiency ever measured in such a organization , " Younes continued .
Magnetars have magnetized fields millions of time strong than any homo - made magnet , but their origin is still unclear . Out of about 2,600 neutron stars known , stargazer have detected only 29 magnetars .
Magnetars do n’t unendingly produce light source and speck but create huge outbursts when the magnetic domain reconfigures to a lower - energy land . The fact that a wind nebula live on many of these is incredible and the detail are report in apaperthat will be print in the Astrophysical Journal .
" The nebula around J1834.9 stores the magnetar ’s energetic fountain over its whole active story , starting many G of years ago , " allege squad phallus Jonathan Granot , an associate professor in the Department of Natural Sciences at the Open University in Ra’anana , Israel .
" It represent a unequalled opportunity to study the magnetar ’s historic activity , opening a whole young resort area for theorists like me . "
