Description

APOD - May 1, 2019 ........ My first APOD so I'm pretty excited.

Since having given up astro-imaging for health reasons and selling my gear, I am finding real joy in processing some of Hubble's amazing image data such as this one, the Cat's Eye Nebula also known as NGC 6543. I am grateful that NASA has given the public free access to their Hubble Legacy Archive which is chucked full of amazing stuff! Thank you NASA!

The Cat's Eye Nebula was one of the first planetary nebulae to be discovered and is one of the most complex planetary nebulae ever seen. Planetary nebulae form when Sun-like stars gently eject their outer gaseous layers, creating amazing shapes. The Cat's Eye Nebula, also known as NGC 6543, is a visual "fossil record" of the dynamics and late evolution of a dying star. It is estimated to be 1,000 years old. (Technical info from NASA Hubble Space project)
