White dwarf by biggauge
I had to use photoshop a little on this one, something I really don't enjoy doing. This is a concept piece of a mechanical civilization that hollows out planets for their recources and has begun to colonize the surface of a white dwarf star to feed off of. It is theoretically possible you know, white dwarfs are much cooler than other stars yet still give off tons of energy. Thus ends the science lesson for the day.
