IC 1795 – The Fishhead Nebula
I don't need to explain how the beautiful nebula in this image got its name. Finally, I've found a celestial object that truly lives up to its name. This image of the Fishhead Nebula, located in the star-forming region where the constellation Cassiopeia is located, is formed by light-reflecting clouds of interstellar gas and dust.
The nebula's colors are thanks to special filters used by the Hubble Space Telescope. These filters color the electromagnetic spectrum of the targeted element, that is, the color spectrum created by photons when they strike it. The order of the filters here is blue, green, and red, respectively, for oxygen, hydrogen, and sulfur atoms.
The Pisces Head Nebula is located in the Perseus arm of the Milky Way Galaxy, right next to IC 1805, the Heart Nebula. It is 6,000 light-years away. At this distance, the image shows a field of view 70 light-years across.
