This one reminds me a little bit of the memorable space invader of Abell 68 from a while back.

At z ~= .537, this one is less distant than the previous one, and it seems to have a lot less stuff in the frame. The redshifting was less noticeable during processing. I am surprised it's not closer than that, really, because the colors seemed to fall out of the data quite naturally. I wish I had paid more attention to actual measurements for these things earlier. Sometimes it's interesting to read about how they are measured. The bright blue lensed galaxy here was measured at z = 1.72; one of the reasons they are useful is because they are magnified quite a bit. Gravitational lenses are nature's little helpers.

This one seemed extra red. It just felt like I had to do more work to get the colors even close to balanced. Maybe it's a bit more redshifted than some of the others. I really ought to look up z before I do each one... according to its entry at Simbad, this one has a spectroscopic z of around 0.659—pretty far! Don't ask me what that is in light years. It's much easier to just say it's far... for reasons. Deep, cosmological reasons.
Note the bright blue arc. I find this is an excellent example because each image of the galaxy is so easy to discern because it contains a repeating pattern. Three times, in fact. How does that work? If you look closely you can see that it is three mirrored and stretched images of the same galaxy.

Another tiny piece of the sky with some easily visible spacetime curvature. Spacetime curvature... time itself is warped. From a photon's perspective, there is no time, but here it is, showing us.
