Creepy or cool: planetary nebulae that look like eyes

Here are several pictures of planetary nebulae.  Many of them look like eyes staring back at you. Is this creepy or cool?  Feel free to comment below.

A planetary nebula (plural: nebulae) has nothing to do with planets. Astronomers are strange when it comes to naming things. Oftentimes, an object or phenomena gets named because of what it looks like (or what astronomers think it is), only to be waaay off base. Planetary nebulae got their name because they looked like hazy planets in gentleman scientists' early homemade telescopes. Fr'ex, the Saturn Nebula, which looks like the planet Saturn.

Really, planetary nebulae are the ionised gas clouds that got expelled at the death of a low-mass star. Towards the end of its life, a star puffs up in its red giant phase, only later to blow away all that matter, leaving the slowly cooling corpse known as a white dwarf. That matter expands through the interstellar medium, glowing brightly from the energy radiated from the white dwarf.  Planetary nebulae don't last long, often only a mere five to fifty thousand years or so.
