Exploding star are always a mess to behold , but not all supernovae are created adequate : Some , for instance , may give birthing to 1000 of worldly concern - similar worlds .
Shown above is a sour - coloration picture of the interstellar junk swarm Sagittarius A East , located 26,000 promiscuous year away toward our astronomic center . It ’s the remains an gist - collapse supernova that took place 10,000 years ago , one that spewed away enough debris to make up to 7,000 ground - corresponding planet , concord to the astronomerswho pieced it together . Whoa .
This rare glance of an exploded star ’s entrails was fascinate using NASA ’s Stratospheric Observatory for Infrared Astronomy ( SOFIA ) , the human beings ’s expectant airborne astronomic observatory , which basically consists of a monumental telescope strapped to a modified Boeing 747 . Remnant dust from the supernova ( prove above in whitened contour line ) , was map based on infrared emissions , or heat signatures left over from the ancient burst .

What ’s significant and new here is how we can see stardust escaping the scene of the crime , ooze out into infinite where it ’ll provide the in the altogether materials for newfangled celestial physical structure to coalesce . According to NASA :
Astronomers already had evidence that a supernova ’s outward - go jolt waving can develop significant amount of rubble . Until now , a key interrogation was whether the new soot- and sand - like dust mote would endure the subsequent inward “ rebound ” shock wave generate when the first , outward - moving shock wafture collides with surrounding interstellar petrol and debris .
“ The dust outlive the later outpouring of shock wave from the supernova explosion , and is now flow into the interstellar medium where it can become part of the ‘ germ textile ’ for unexampled whiz and planets , ” Lau explained .
The finding also offer strong evidence that the “ dustiness ” of young , distant galaxies may be the result of supernova — a speculation that until now lacked data-based support .
The notion that we ’re all just stardust may bealmost clicheat this point , but still , it ’s singular that we now have the technology to see the grounds strewn all over the cosmos .
