Cat's eye nebula



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
