Death of a Superstar

"Puppis A," used to be a massive star (not unlike John Wayne, or Mae West). Now its life ends as a supernova, blasting its outer layers in a huge shockwave into space. Light from this super-explosion first reached Earth just a few thousand years ago, a mere second as measured in space/time. Now they're all gone, John, Mae, Red Ryder, Little Beaver, and Puppis A.
