Summary

DescriptionNGC 6946.jpg	English: NGC 6946 is a medium-sized, face-on spiral galaxy about 22 million light years away from Earth. In the past century, eight supernovas have been observed to explode in the arms of this galaxy. Chandra observations (purple) have, in fact, revealed three of the oldest supernovas ever detected in X-rays, giving more credence to its nickname of the "Fireworks Galaxy." This composite image also includes optical data from the Gemini Observatory in red, yellow, and cyan.

En el siglo pasado, se han observado ocho supernovas a explotar en los brazos de esta galaxia. Observaciones de Chandra (púrpura) han, de hecho, reveló tres de las supernovas más antiguas jamás detectados en rayos-X, dando más crédito a su apodo de los "Fuegos artificiales de la galaxia." Esta imagen compuesta también incluye los datos ópticos del Observatorio Gemini en rojo, amarillo y cian.
