The Ring Nebula - M57
The Ring Nebula is an entire light year across and was born from an exploding Red Giant Star. Evidence of the death of this star can be seen around of the nebula in the top image. The dark-red wave-like filaments propagating from the nebula are the outer layers of a Red Giant Star. The outer waves formed when the star ejected fast moving material and it collided with slower moving material. The Ring nebula will expand for the next 10,000 years as it grows dimmer and larger.
