First discovered by William Herschel on February 15th 1786 this planetary nebula is a real gem of the night sky. It sits 3300 light years from us and contains some mysteries that remain unexplained today. The dying star appears to have ejected its material to form the nebula at intervals of a few hundred to a few thousand years. This pattern of ejection remains unexplained today. Although, only one central star is observed another mystery is that the pattern of ejection has lead to the theory of a binary star system, but the second star has not been observed.
