The Surface pt. III

Still fine-tuning my planet & surface scenes to get more details out of them.
All in POV. Total rendering time: 09h 42m 43s (with FX-8350). :)

Oops, I mean, still sending new and improved probes down there to get more
detailed visuals from a yet pretty unknown world. :D

   Looks alien, indeed. Maybe the water (if that's water) needs more
credible normals (not so regular).

   Are you going to upgrade the camera to a color one for the next probe? ;)

Nice image ! I can't wait to see what kind of creature live on this planet
(hoping your next probes will survive to the encounter ;) )

I feel like probably all NASA people must feel when the first images 
from a probe come in. Tantalising and... frustrating! We want to see 
more, but have to cope with the technology and the sheer distance to the 
alien world. You certainly have caught the mood.

I agree with Jaime about the water.

But is it water ? Given the strangeness of the whole scene (the sky, the horizon
curvature, the colors) I like it as it is, it matches the whole atmosphere. It
maybe some kind of frozen hydrocarbon under low pressure and gravity
conditions... ;-)
It reminds me this superb book of pictures from Mars :

Some pictures looks so unreal while they are so real !!

True, but you have to realise that, whatever the planetary setting, the 
physical boundary conditions under which structures are created are the 
same. So, dunes on Mars are similar to dunes on Earth. Similarly, that 
is why it is possible to infer the wet condition of Mars in the past 
just by studying the fossilised structures outcropping near Curiosity.

Now, to come back to Pekka Aho's unnamed world, the liquid (?) surface 
looks strange either for a liquid as for a frozen one. If they are 
ripples, we can infer there is some kind of atmosphere and hence some 
wind. There is much to discover still! See? we are already building 
assumptions on the few data we have. We have to wait for the next batch 
of photographs to learn more :-)

I think it could be liquid with strong convective currents.

It looked a lot like there was some sort of vibration disturbing the surface -
either that, or it was, or was thick with, some sort of organism or substance
which gave it that crinkly molded-over look, like something excavated from the
bottom of the refrigerator or under the cushion in a bachelor pad.  :D

Perhaps some geologic disturbance is occurring, or this stuff got uncorked and
is interacting with the atmosphere - difference in temperature, pressure, or
other attribute influencing the surface.

Looking forward to forthcoming images transmitted from the surface  :)

Not necessarily. Do you know the Ice Spikes ? The surface get disturbed only by
irregularities in the water :
https://en.wikipedia.org/wiki/Ice_spike
It happens once in my refrigerator and I've been very surprised as I didn't knew
this phenomenon.

Alternate explanations coming forth. Excellent Gentlemen! :-)
