Abell 39 – Planetary nebula

Description:

Abell 39 is a planetary nebula in the constellation Hercules. With its 2.5 light-years radius, it’s relatively large for a planetary nebula, and it’s about 6,800 light years away from us. This shell of gas ejected by the star that can be seen in the center continues to expand at a speed of 35 km per second.

This bubble is relatively faint and difficult to photograph and I’m glad I succeded. Its unreal appearance is another example that sometimes reality surpasses fiction.
