Lift up your eyes on high, and behold who hath created these things... Isaiah 40:26
"The Kuiper Belt, a vast disk brimming with icy bodies including 
Pluto and located just beyond Neptune’s
orbit in our solar system, exhibits an intriguing color palette ranging
from stark white to deep reddish hues on its objects.
This distinctive
color range, unique among all solar system populations, has long
remained a mystery.
...Chemistry researchers has
replicated the environment in the Kuiper Belt to discover what is
causing the array of colors in hydrocarbon-rich surfaces of Kuiper Belt
objects, providing a solution to a long-standing problem in
astrophysics.
**Aromatic
(organic molecules with fused benzene rings) structural units carrying
up to three rings, for example in chemical compounds phenanthrene,
phenalene, and acenaphthylene,
---connected by hydrogen-deficient bridges
among each other were found to play a key role in producing reddish
colors.
The UH experiments demonstrated the level of molecular
complexity of galactic cosmic rays processing hydrocarbons and provided
insight into the role played by ices...."
