it doesn't show it very well in the video, but the first lens is a spherical object, while the second is a more elongated object, which produces the difference in what is seen from our point of view
this is not due to refraction [snell's law]. light is not slowing down. the basic idea is this. light travels along a straight path. put the path that it is on - space - has been curved by the massive force of gravity by the galaxy. so the light will 'bend' around the galaxy and hit our eyes. if the object far away and the galaxy in the middle are perfectly in line with each other, you can get multiple images of the far away object or even a warped ring around the whole galaxy.
@fishspawned i already got my answer the other day anyway but youre mostly wrong, sorry. yes, light does slow down as it gets closer to the massive bodies then speeds back up the farther away it gets. its one of the basic concepts of relativity.
lol the third is dark matter.

Hi, I don't understand what kind of lenses are the first 2 (the 3rd is a globular cluster, isn't it?)
