Description

A 12000 AL dans la constellation du Cocher l'amas stellaire NGC 1893 et la nébuleuse à émission IC 410

Renseignements sur cette constellation en collant le lien ci-dessous dans votre navigateur :
http://fr.wikipedia.org/wiki/Cocher_%28constellation%29

La nébuleuse abrite les "têtards", constitués de gaz et de poussière plus froids et denses, mesurent environ 10 années lumière de long, et abritent potentiellement des étoiles en formation.

Pour avoir une idée de la dimension apparente de cette nébuleuse dans le ciel dites vous que l'image pourrait contenir 3 fois la pleine Lune.
