Human like faces in an Astronomical Photo taken by the Hubble Telescope

Hi folks!!
Sorry for the short break from posting...
But I am here to compensate for that, with this interesting photo...

Just now, I was uploading some wallpapers in my other blog, and while uploading some photos of various galaxies(taken by Hubble), I ran into this interesting photo... Let's see if you can find out what makes it interesting..

GOT IT NOW??
Oh yes!! they look like human faces right?!?!?

In fact, the one on the right looks more human (even having something like a beard and wearing a dress like the ones worn by Royal People in the movies...),

While the one on the left, looks more like Arnold Schwarzenegger's robotic face from the movie "Terminator", (you know with that glowing eye and showing all the teeth.. LOL..)

I am just amazed at spotting this.. I got these photos long back , but only now did I notice this beauty... There is also another one of these photos, which looks more like a hooded figure riding a horse (i tried to outline the figures, but ended up making a mess of it.. hope you can spot it yourself..)

So, these photos only show us that, there is no better artist than our own Mother Nature!!
