This is What the Solar System Really Looks Like

At first glance, it looks like something from an alien autopsy. A strange organ cut from a xenomorph’s thorax, under the flickering lights of an operating room in a top secret government facility, with venous tendrils dangling down to the floor, dripping viscous slime.
