The supernova's remains are estimated to be roughly 23,000 light-years away. A type "Ia" supernova (occurring in systems where two stars orbit each other), it was a white dwarf, turning supernova as its dense core had stopped creating nuclear fusion reactions. To this day, no other supernovae inside the Milky Way have been identified with certainty. Its light may have faded, but Kepler's supernova still burns brightly in the minds of star gazers as a result.
