Evaporated nebulae and their star patterns
This picture seems to show one of possible conditions:
- Stars popping out of the dark nebulae reflecting the organization of a central star (or bright green knot?) surrounded by a ring of stars (or green knots), which in turn have smaller rings of stars.
- Stars born in the active green nebulae that have dissipated the gas and dust that gave them birth.
Burning question: Are the rings that I see equivalent to bubbles and should I identify them as bubbles?
