Conceptual animation demonstrating the process of spectroscopy. The first animation demonstrates the general concept of visible-light spectroscopy by which white light is separated into its component wavelengths (colors) using a prism. The second animation demonstrates how this idea is applied to the discovery of methane in Mars' atmosphere. Because it absorbs specific wavelengths of electromagnetic energy, methane has a 'fingerprint' that can be seen as missing lines on the resulting spectograph.
