Comment: |
M57 is one of the best known planetary nebulae. Ring Nebula is actually shaped like torus, and we look at it down one of its poles. Torus surrounds its central star, which is a planet sized white dwarf. Hot gas near the energizing central star is blue in color, progressively cooler gas at greater distances is green and yellow and the coolest gas along the outer nebula boundary is red. The nebula is more than 1 ly across and 2.3 kly distant. |
