The first version was considered to be too dark.

The second version was just the first version brightened up a bit.

The third (current) version was reworked to get the desired gravitational lensing effect around the wormhole. This was done by making a skybox in SpaceEngine with a black hole (to generate the lensing) and then covering the black hole with the wormhole entrance in Blender.
