HD 184738


HD 184738This is HD 184738, also known as Campbell’s hydrogen star. It is surrounded by plumes of reddish gas—the red and orange are the glow of surrounding gases such as hydrogen and nitrogen. The star is at the center of a small planetary nebula, and very bright in the infrared part of the spectrum. The surrounding dust is probably very similar to the material from which the Earth formed. The origin of this dust is uncertain.
