BEHIND THE IMAGE
Notes from the session
This image is a false colour representation of hydrogen-alpha, sulfur-II and oxygen-III emission-line clouds, mapped to red, green, and blue respectively. An emission line will appear in a spectrum if the source emits specific wavelengths of radiation. This emission occurs when an atom, element or molecule in an excited state returns to a configuration of lower energy.
