Multiwavelength Milky Way


Imagine that you are looking up at the night sky and can see the arms of the Milky Way Galaxy bisecting the sky. The image of the sky labelled optical in this graphic is what you would see with your eyes. Now, observe the images of the same view of the Milky Way, but in through the lens of a telescope that sees in a different wavelength than our eyes. The amount and type of information, or data, available in each waveband varies as illustrated in this graphic. You can see why it is so important that we look at the universe through eyes that see wavebands other than optical light.
