Summary

Description

Italiano: Image of M57/NGC 6720 (The Ring Nebula) from NASA's Spitzer Space Telescope.

"Spitzer's infrared array camera detected this material expelled from the withering star. Previous images of the Ring Nebula taken by visible-light telescopes usually showed just the inner glowing loop of gas around the star. The outer regions are especially prominent in this new image because Spitzer sees the infrared light from hydrogen molecules. The molecules emit the infrared light that they have absorbed ultraviolet radiation from the star or have been heated by the wind from the star."
