Cat's Eye Nebula(NGC 6543) is a planetary nebula in the constellation
of Draco. Structurally, it is one of the most complex nebulae known.
It was discovered by William Herschel on February 15, 1786, and was the
first planetary nebula whose spectrum was investigated, by the English
amateur astronomer William Huggins in 1864.
Modern studies reveal several mysteries. The intricacy of the structure
may be caused in part by material ejected from a binary central star,
but as yet there is no direct evidence that the central star has a
companion. Also, measurements of chemical abundances reveal a large
discrepancy between measurements done by two different methods, the
cause of which is uncertain.
I painted this nebula be cause I liked it's aspect.
This nebula is a verry beautiful space object
