Artificial lighting from cities and towns brightens the night sky and reduces contrast, making faint celestial objects harder to observe. While streetlights improve visibility on the ground, they create skyglow that obscures delicate deep-sky structures. Emission nebulae differ from star clusters, galaxies and reflection nebulae because they radiate light at very specific wavelengths. Instead of producing a broad spectrum, they emit distinct spectral lines.
