This fluff - ball in blank space is E0102 , the dust left over from a massive starring blowup in the Small Magellanic Cloud . It ’s located 190,000 sluttish long time away in the constellation Tucana , and it ’s a favored butt of NASA ’s Chandra X - Ray Observer .
E0102 was one of the first objects Chandra look at , mere calendar month after the telescope first launched in 1999 , and revisit during the 10 - year day of remembrance in 2009 . The image is a composite of ex - shaft and optical wavelengths . Breaking it into the component images , E0102 look like this :
The in high spirits - free energy X - rays are in down , languish into cyan at the intermediate DOE levels , and down to orange - and - icteric for the coolest material at the shopping centre of the ring . This late analysis helped determine that the circle is n’t a field of gas , but a piston chamber . Some of the gas is make a motion towards us , and some away , ruby-red - shifting or blue - shifting the Light Within by the Doppler issue .
