Inside the Great Nebula in Orion
This 12.5hr exposure peers deep inside the Great Nebula in Orion. The ionisation of Hydrogen atoms by ultra violet radiation, emitted by massive stars deep inside the nebula, produce the predominantly red hues. Clouds of fine dust appear blue-grey due to the scattering of short visible light wavelengths in a process known as Rayleigh scattering. Cold foreground dust and dark molecular hydrogen create a fine intricate web of obscuring dark clouds. The combined atomic and optical processes coordinate to produce this stellar kaleidoscope of wispy details and colours.
