1604: Supernova 1604 becomes the most recent supernova to be observed in the Milky Way. The supernova would eventually become known as Kepler's Supernova or Kepler's Star, after German astronomer Johannes Kepler, one of the first write about it. Observers used only their eyes to study it, because the telescope had not yet been invented. In the first part of the 2000s, astronomers used NASA's three Great Observatories to analyze the supernova remnant in infrared, optical and X-ray light (pictured).
