- This image was taken in the northern constellation of Casseopeia. The reddish color is very bright and illuminating. The light is reflecting off gases in space as well as space dust. After learning about the different colors that gases reflect, it was interesting to learn that hydrogen produces a red glow. on Earth however why does hydrogen not glow red naturally. Why do its electrons have to be excited with electricity to create the color. Is there some sort of electromagnetic radiation in space causing the color? The color manipulation helps to aid our visualization of picture. The image coming from the telescope could not have been this high of resolution. The narrow filter stated in the descriptuion was very helpful in creating this picture.
