NASA's Hubble Space Telescope shows NGC 3314. The two galaxies look as if they are colliding, but they are actually separated by tens of millions of light-years, or about ten times the distance between our Milky Way and the neighboring Andromeda galaxy. The chance alignment of the two galaxies, as seen from Earth, gives a unique look at the silhouetted spiral arms in the closer face-on spiral, NGC 3314A.

Thats a really cool picture!!!! I find it amazing how one Galaxy has mostly blue stars, and the other has bright whites, yellows, etc... Does that mean One is much older than the other.??
a star moving away from us would look slightly more red than usual because the light waves that reach us are drawn out due to the motion of the star. And conversely, a star moving towards us would look slightly more blue than usual
