The Helix planetary nebula is one of the nearest: “only” 700 lightyears distant.
The central old #star is losing its external layers creating the nebula.

The Helix planetary nebula is one of the nearest: “only” 700 lightyears distant.
The central old #star is losing its external layers creating the nebula.
Our sun will create also a planetary #nebula… in 4 or 5 billion years.
