This beautiful nebula is located about 1,500 light-years away (light-year, the distance light travels in one year, is about 9.46 trillion km). The appearance seen through a telescope resembles the egg of a robin, which is why it is also called the Robin's Egg Nebula.
The cosmic cloud is currently about 3 light-years and is located inside the boundaries of the furnace constellation in the southern hemisphere. The nebula classified as NGC 1360 shows a brief phase where an old star meets its end, rather than the birth of a new star.
In fact, the central star visible in the nebula is known to be a binary system consisting of two white dwarfs. These stars have a lower mass than Taeyang but are much hotter and emit strong ultraviolet radiation. This ultraviolet radiation removes electrons from the atoms in the surrounding gas cloud, ionizing them. The bluish-green hues seen in this image are produced by the strong radiation emitted as electrons recombine with doubly ionized oxygen atoms.
