APOD 2.2

         Nebulas are so visually appealing. They resemble a somewhat gas cloud but emit colors and take extraordinary shapes. Nebulas to me are like the aurora lights found on Earth. I assume that the different gases found in the nebulas are a portion of why the different colors are emitted. This specific nebula was found to have hydrogen in it. Im not sure how they can determine that from a telescope, so I would hypothesize that the colors determine the compound. Similar to neon lights, the different gases when excited have specific color properties.
