Very nice find, quite interesting indeed. Thanks for putting this up there.....It is truly amazing isnt it? Makes you realize just how small we
actually are.

Optical data of the supernova remnant and its accompanying star field, taken with the Hubble Space Telescope, are composited with X-ray images from the Chandra X-ray Observatory. The supernova that resulted in the creation of SNR 0509-67.5 occurred nearly 400 years ago for Earth viewers. The bubble-shaped shroud of gas is 23 light-years across and is expanding at more than 11 million miles per hour
i wonder what forces stopped it from being a perfect circle
This is the perfect picture to be stuck in my head when I close my eyes
