So pretty, what is it?

Some sort of life form judging by the symmetry.

From wiki:

Symmetry in biology is the balanced distribution of duplicate body parts or shapes. In nature and biology, symmetry is approximate. For example, plant leaves, while considered symmetric, rarely match up exactly when folded in half. Symmetry creates a class of patterns in nature, where the near-repetition of the pattern element is by reflection or rotation. The body plans of most multicellular organisms exhibit some form of symmetry, whether radial symmetry, bilateral symmetry or "spherical symmetry". A small minority, notably the sponges, exhibit no symmetry (are asymmetric).


Many jellyfish have four canals and thus exhibit tetramerous radial symmetry. This form of radial symmetry means it can be divided into 4 equal parts.

Not a jelly fish...alien...maybe not carbon based...

Oh, like how we have two arms and two legs and two eyes. Symmetry, right?

Yep. That isn't necessarily a pointer to an organism - we design much of our machines etc along those lines - cars, planes, etc....so, maybe rather than a life form this might be a device of some alien or future etc etc etc.

A device? To do what?
