How ’s this for a crazy astral event : an perfectly mammoth star about 90 time the size of our sun has been shot out of its birthplace and is currently rocketing across space at 250,000 miles per hour . Hot damn !
First , the size of it : stars can reach about 100 time the size of it of our Lord’s Day before collapse under their own free weight , which get this one of the biggest stars ever recorded . It ’s 180 octillion tons , which is a big number than your shrimpy brain can comprehend . And it ’s moving fast .
How fast ? Well , it ’s covering the distance between the Earth and the Moon every hour , a trip that submit Apollo three day .
So how ’d a star this big get moving so tight ? have ’s letBad Astronomyexplain :
The two genius orbit each other at high speed , and when one blow up it lose so much mass it ca n’t hold onto the other genius . Like an athlete spinning around for the pounding toss and then allow go , the hotshot gets shot away at high speed . The affair is , the clustering itself is too young to have seen such a supernova a million years ago , when the star must have commence its flight . Plus , there ’s no indication of the character of a mess leave by such an explosion .
So the star must have been ejected when it reacted gravitationally to other mavin . If you take three mavin , say , and let them interact , the least massive one will get flung away . Take a few twelve and you get a beehive of body process , with several champion tossed out , some with very high speed . The thing is , this hotshot has 90 times the Sun ’s mass ! That mean the stars left behind are even more massive … and we do see several stars in the clustering with masses as high as 100 – 120 times that of the Sun .
Definitely point on over toBad Astronomyfor the full summation and more pictures and to be made to feel small and insignificant and full of wonder . [ Bad AstronomyviaKottke ]
