NGC 2392 is also referred to as Clownface Nebula or formerly Eskimo Nebula, because a white dwarf is located in the middle of the nebula, surrounded by a bright bubble of material moving away from the star. This makes the nebula look like a face with a parka around it. What’s interesting about this nebula is that the dying star in the middle is very similar to our Sun, so it can serve as a perfect reference to the ultimate fate of our Sun in about five billion years.
