Are you ready for more stereo vision? This haunting Hubble Telescope image has been visualized for dimension by the one and only Jukka Metsavainio and gives us a look at one of the most complex planetary nebulae ever photographed. Inside NGC 6543 - nicknamed the "Cat's Eye Nebula" - the Hubble has revealed delicate [...]

That is so cool! But it can be a bit of an eyestrain if stared at too long.

I can't wait until 1920 x 1200 res contact lenses come out.

Jukka Metsavainio... credit were credit is due.... brilliant.

Yes I later thought my post in the questions page was a mistake...

I would like a explanation as to how this is done ?

Is it just two images six months apart to give us the three dimensional view. ?
Or computer generated imaging. ?

Very good... now how to print that.... LOL.:)

And... :) NOW I FEEL LIKE AN IDIOT:) If I had looked at this properly I did not need to ask what has been explained so well... Sorry for the gaff.:(

Basically yes, by taking a snap shot of a distant object from opposite sides of the earths orbit, you get a binocular effect from a basline of 2AU's. This should actually be a good enough paralax that close by galaxies should be able to be 3'd in this manner as well, to a lesser degree.

I think this is the first application I've seen of this, though I know it's been discussed as being possible for some time.
