Watching a Supernova Remnant Grow


This time-lapse video shows the movement of a supernova remnant that erupted approximately 1,700 years ago. The gaseous remains of an exploded star named 1E 0102.2-7219, is in the Small Magellanic Cloud, a satellite galaxy of our Milky Way. The opening frame shows ribbons of glowing gaseous clumps that make up the remnant. The video then toggles between a pair of black-and-white images taken 10 years apart, showing subtle shifts in the strands of gas over the decade.
