It is an aging star about 3,000 lightyears distant, entering its Planetary Nebula phase of evolution.

Dust particles in the expanding cloud scatter and reflect the starlight making the beams visible. The sharpness of the HST image reveals a wealth of detail which will help to understand this complex and spectacular part of the stellar lifecycle .
