A comparison of the fluxes of both PNs at different wavelengths indicates that they are intrinsically similar in size and brightness but are located at different distances. We find that the stellar blue and visual (continuum) fluxes, the H ...

Astronomical spectroscopy
Astronomical spectroscopy is the study of astronomy using the techniques of spectroscopy to measure the spectrum of electromagnetic radiation, including visible light, which radiates from stars and other hot celestial objects. Spectroscopy can be used to derive many properties of distant stars and galaxies, such as their chemical composition, temperature, density, mass, distance, luminosity, and relative motion using Doppler shift measurements.
