APOD 2.3

See Explanation.  Clicking on the picture will download
 the highest resolution version available.
Aside from its stunning beauty, I chose this photograph because my most recent posts have been limited to aurorae or galaxies. This photograph features the Cat's Eye Nebula, the remnants of a dying central star similar to our own sun. This photograph was taken by the Hubble Space Telescope, featuring a star whose cosmic eye is over half a light year across. Our sun will go through this stupendous phase in approximately 5 billion years.
