SN 1604, also called Kepler's Supernova, is a supernova in the constellation Ophiuchus that appeared in October 1604 and was visible to the naked eye, even in daylight for a time. It is the most recent supernova seen with the unaided eye in the Milky Way. The German astronomer Johannes Kepler observed it carefully from Prague and described it in his book De Stella Nova in 1606, which is why it carries his name, although other astronomers, including Galileo, also studied it. The appearance of a new star challenged the old idea of an unchanging heavens in the sphere of the stars. Modern observations identify a remnant of the explosion, which is thought to have been a Type Ia supernova.
