There ’s no smoke without a fire , and there ’s no supernova remnant without some evidence of a past supernova blowup . TheJellyfish Nebula , also known as IC 443 , is a supernova end that has so far remained without a culprit , but scientists have last observed where the nebula bug out from .
uranologist have come across a pulsar ( a rapidly rotating neutron star topology ) on the bound of the nebula by observing IC 443 using theChandra X - ray telescope . The object is surrounded by a tintinnabulation of fabric and it ’s emit a powerful honey oil . The pulsar has a comet - similar tail of dispersed hot accelerator pedal , which is due to the fact that the star is moving at 800,000 klick per hour ( about 500,000 miles per minute ) .
The fag end of the pulsar is misaligned compared to the flight of the pulsar , which could be due to interactions with the material of the nebula . The fundament has also been put forward as an denotation that the pulsar is move inside the nebula and it ’s not the end of the original supernova . The tail does n’t show any shock Wave ( likes a sonic boom in the cloth ) , point that the pulsar is part of the nebula and the cinder of the supernova that make it .
The Jellyfish nebula is 70 light - age across and it is 5,000 wakeful - years from Earth . It probably formed 30,000 years ago ( although some stargazer have suggested a much earlier age of 3,000 old age ) . The new composite double expel by NASA give away a rotary structure made of particles from the pulsar wind suddenly being slow down .
Pulsars mold when a star more massive than the Sun survive supernova . Stars at the end of their lives cave in on themselves , and if their tidy sum is veracious ( too big and it will become a black hole ) , an physical object made exclusively by neutron will be left behind after the explosion . pulsar are incredibly obtuse : a teaspoonful press about 5,000 million measured tonnes ( 5.5 billion US stacks ) .
The enquiry is published inThe Astrophysical Journal .
