Hubble Time-Lapse Video Reveals Supernova Remnant Expansion

This time-lapse video shows the movement of a supernova remnant—the gaseous remains of an exploded star—that erupted approximately 1,700 years ago. The stellar corpse, a supernova remnant named 1E , met its demise in the Small Magellanic Cloud, a satellite galaxy of our Milky Way. Credit: NASA, ESA, A. Pagan (STScI), J. Banovetz and D.
