Supernova explosion shells — SNRs — are not the easiest objects on the sky to spot, but they make up for it by providing us with all the chemical elements we need to build our telescopes and astro-cameras — not to mention our wives, kids, dogs, cats, and ourselves. Even if we can't see them visually, they create beautiful astronomical photographs for us to enjoy. How SNRs manage to provide us with the chemical elements we require to live is a complex tale for those nights when we are stuck indoors and the cold winds are howling. Sky Candy has obliged by posting two new stories of the supernova remnants Simeis 147 in Taurus, and the boggling complex Vela supernova remnant visible from south of 40 degrees:
