Looking at the Saturn Nebula in 3D

This visualisation shows the three-dimensional MUSE data on the bright planetary nebula NGC 7009, also known as the Saturn Nebula. Each slice is presented in sequence shows a view of the object at a different wavelength. At certain wavelengths, corresponding to emission lines in the spectrum from hydrogen, oxygen and helium, the object glows brightly and strange structures are revealed. At the end these emission line views are combined to make a colour picture of the object.
