 Let's take a closer look at what one of these brown dwarfs looks like. Astronomers using the Spitzer and Hubble space telescopes have probed the stormy atmosphere of a brown dwarf just 35 light-years away. It has a probable atmosphere, making it a good example of the planet-like characteristics of brown dwarfs. The probe's result revealed offset layers of material as indicated in the diagram. For example, a larger, bright patch in the outer layer has shifted to the right in the inner layer. These variations are the result of different layers or patches of material swirling around the brown dwarf in windy storms as large as the Earth itself. We find that brown dwarf atmospheres can be similar to Jupiters, except that instead of raining ammonia, brown dwarfs rain molten iron droplets.
