this is one of the cooler things i've seen in a while: stereo astronomy images created by J-P Metsavainio at astro anarchy.
remember those images from 15 years ago or so, that looked like spotty noise, but if you adjusted where your eyes focused, you could see a three dimensional image pop out?? that's what J-P Metsavainio has done with images of astronomical objects! he explains how to view the images on his website.
i remember the first time i saw these types of images at the ohio state fair. i couldnt figure out what everyone was staring at, but the moment i finally figured out how to "see" them and watched the statue of liberty pop out of the flat image - i was amazed!
now, J-P Metsavainio has created a very interesting method for imagining the 3D structure of astronomical objects that we can only view from one direction!
