In processed astronomical images, how is the true spectral signature of an emission nebula revealed?
Answer
Software assigns specific captured wavelengths (like ionized hydrogen red) to visible color channels
A specialized camera sensor captures distinct wavelengths emitted by gases, and then software assigns those specific light signals to visible color channels (like red, green, or blue) to reveal the true spectral signature of the gas.
