Joliiiiii ! La nébuleuse de la Bulle ou Caldwell 11, est une nébuleuse en émission située dans la constellation de Cassiopée.
Je cite:
What created this huge space bubble? Blown by the wind from a star, this tantalizing, head-like apparition is cataloged as NGC 7635, but known simply as the Bubble Nebula.
The featured striking view utilizes a long exposure to reveal the intricate details of this cosmic bubble and its environment.
