What it is

A shell blown into the surrounding gas by the wind of a single young star about 45 times the mass of the Sun.

The picture hangs at that distance facing Earth, as large as it is on the sky; how deep the object is cannot be seen, so it is flat.

Bubble Nebula

The Bubble Nebula, also known as NGC 7635, Sharpless 162, or Caldwell 11, is an H II region emission nebula in the constellation Cassiopeia. It lies close to the open cluster Messier 52. The "bubble" is created by the stellar wind from a massive hot, 8.7 magnitude young central star, SAO 20575 (BD+60°2522).
