  Hubble Cat's Eye Nebula
NGC 6543The alluring Cat's Eye nebula lies three thousand light-years from Earth. A classic planetary nebula , the Cat's Eye (NGC 6543) represents a final, brief yet glorious phase in the life of a sun-like star. This nebula's dying central star may have produced the simple, outer pattern of dusty concentric shells by shrugging off outer layersin a series of regular convulsions. But the formation of the beautiful, more complexinner structures is not well understood .Seen so clearly in this sharp Hubble Space Telescope image, the truly cosmic eye is over half a light-year across. Of course, gazing into the Cat's Eye , astronomers may well be seeing the fate of our sun, destined to enter its own planetary nebula phase of evolution ... in about 5 billion years .
