I’ve written many times about the power of looking at different wavelengths of light to study different properties of the universe.  From a visualization standpoint, there are other techniques that give you additional power when imaging.  More than just the wavelength of light you’re using to show the detail, you can choose the range of wavelengths to bring forward certain features while suppressing others. The aptly-named spaghetti nebula, shown above, is a great example of this.  A supernova remnant that covers the constellations Taurus and Auriga, the nebula is very large in the sky, covering three full moons worth (love that unit...
