For the first time you can see a galaxy in three dimensions. This is
the galaxy NGC4565 postioned edge-on.
Simply look at the two images below and cross your eyes until the two
images superimpose. You will see the contours of a distant galaxy as if
you were seeing it with your own eyes.
(Of course, since the galaxy is 30 million light years
away and since your eyes are only inches apart, don't expect a whole
lot of improvement over a flat image. Well, what did you expect?
Where in the universe were you going to position yourself so your eyes
significantly different views of a galaxy? Even if you could
travel anywhere you wanted this is as three-dimensional as it can get
if you are going to see the full width.)
