Ultraviolet light (UV) from newborn stars stimulates the remaining hydrogen in the cloud to emit light at the hydrogen-alpha (Hα) wavelength of 656.28 nanometers, creating a glowing emission nebula.

The Southern Ring Nebula was imaged in December 2022 by the James Webb Space Telescope (JWST), which revealed molecular hydrogen gas forming the nebula's "exoskeleton." ...

Thanks to the James Webb telescope, we can now see the nebula with more clarity. As one expert says, ... the star had been converting hydrogen to helium — but it started to run low on fuel.
