Description: |
The bubble from expanding gas depicted above is the planetary nebula PK164+31.1. It is the remaining atmosphere of a sun like star. This star has ejected his outer hull when it runs out of hydrogen. Near the centre of this nebula the remnants of the core can be seen- a bluish and hot dwarf star. This particular photogenic planetary nebula has complex layers of gas which were ejected most likely at different points in time. The structure cannot be fully explained yet. PK164+31.1, aka Jones-Emberson 1 lies in a distance of about 1600 light years and is located in the constellation of Lynx. Even though the nebula itself will pale within the next thousands of years the cetntre white dwarf will survive for billions of years. |
