Galactic supernova or Lumpy Space Princess? You decide. 3C 397, also known by its harder to memorize alternate name G41.1-0.3, is a Galactic supernova with a very mathematical figure. We’re not rocket scientists here, so here’s NASA to explain, ‘Researchers think its box-like appearance is produced as the heated remains of the exploded star – detected by Chandra in X-rays (purple) – runs into cooler gas surrounding it. This composite of the area around 3C 397 also contains infrared emission from Spitzer (yellow) and optical data from the Digitized Sky Survey (red, green, and blue)’.
