Would the sky really be blue?


At that altitude, yes. I used the upper left panel of PIA08112 as a guide. Specifically, the lower right corner of that panel since it was the most sunward direction.

Trying to capture winter at troy.

First my model MER on the floor, flashlight on bed. Then adding the
Calypso panorama and fiddling around in photoshop elements.

Beautiful! I like the spotlight effect when it is just on the floor!

Thanks. Actually it's on a tilted piece of cardboard on the floor. That shot is more dramatic, but less realistic.

Here are some other shots plus an intermediate photoshop version.

Saturn sky....

Starting with a Cassini image (reoriented/rotated, with corners filled in):

I sampled the haze and bits of sky visible in front of the Encke gap, and produced this color palette:

Attached Image

I then enlarged and expanded the palette:

Added some clouds (sampled from the Cassini image):

And completed the scene:

Very nice vistas / renderings. The Titan lake view gives me an idea to try my sky simulation software, previously run with Mars aerosols, to use aerosol data from Titan. I see this reference that can help:

http://www.ciclops.org/media/sp/2010/6514_15623_0.pdf

Both surface and simulated descent views would be interesting to see.

Thank you.

Any attempts to estimate the accurate appearance of the sky of Titan, or any world, would be appreciated.

Several years ago, I did some artwork of the Gliese 581 system. Some could fill in for TRAPPIST-1:

Cloud-shrouded ocean planet (originally Gliese 581d):

Approaching the cloud deck:

Endless swells:

The sky here has a slightly greenish cast due to the high air pressure at the surface (I read about this phenomenon somewhere, but I'm not sure where. I gather that the sky would be green because much of the blue light has been scattered away higher up).

(As you can probably tell, all images above, except the first one with the red dwarf star and planets, are altered photos.)

'Clarified hot Neptune' (originally Gliese 581b):

The temperature of the atmosphere is sufficiently high to prevent the formation of clouds. As a result, the planet's blue color is due almost entirely to Rayleigh scattering.

Some haze offers a bit of relief to the monotony:
