Cassini Saturn Craft bids farewell to icy moon Mimas, making its final close approach & creating this hi-res image

it looks like two images put together
>>
>>8749750
Probably because it really is 3D
>>
>>8749750
Why would they use a model and not CGI if they were faking it?
>>
Space actually looks like shit in reality, films make space look better than it is
>>
>>8749750

>sun is clearly shining from the right to left
>left side that is supposed to be dark is visible

spacelets will fall for this.
wake up sheeple
>>
>>8749769
This. It's doctored. You can see for the right side of the image the craters appear illuminated from well off-right of frame, while for most of the moon center and left it seems to be illuminated from behind the camera (somewhat to the upper left).

Also with no atmosphere, there's no diffuse lighting in space, which looks unnatural to us but is often replicated by CGI graphics engines due to simpler setup and rendering of a point-light source.

The sun is shining from the right and saturn is reflecting the sun light from the left you fucking idiots. It's a moon, quite close too.

This is utter bullshit.

>>8749750
Because it's very easy to model planets/satellites.

actually the earth is cover by a dome so this image is fake
>>
>>8749750
Looks like HDR exposure

a word of reason.

Those of us who care applaud thee, esteemed anon.

If you actually read the link OP included you'd see that it's a mosaic.

>Two versions of the mosaic are provided. In one, the left side, which is lit by reflected light from Saturn, has been enhanced in brightness in order to show the full surface. The second version features more natural illumination levels (Figure 1).

>Imaging scientists combined ten narrow-angle camera images to create this mosaic view. The scene is an orthographic projection centered on terrain at 17.5 degrees south latitude, 325.4 degrees west longitude on Mimas. An orthographic view is most like the view seen by a distant observer looking through a telescope.

>This mosaic was acquired at a distance of approximately 28,000 miles (45,000 kilometers) from Mimas. Image scale is approximately 820 feet (250 meters) per pixel. The images were taken in visible light with the Cassini spacecraft narrow-angle camera on Jan. 30, 2017.

So it looks weird because it has had the dark side brightened. It is NOT planetshine. Pic is the second version mentioned.

What is "Huge fucking reflective palnet ober there?"

I'll take The Bleeding Obvious, again, for 200, Alex.
>>
>>8750517
>It is NOT planetshine.

Dude, it literally is, planetshine is where the light on the side away from the sun is coming from, so that they can take a picture of it and make a mosaic. Your quoted text even says so:

" In one, the left side, which is lit by reflected light from Saturn"
>>
>>8750760

Other planets don't have highly reflective water oceans acting as mirrors so that explanation is pure bullshit.
>>
>>8750775
I should've been more clear with that sentence, I knew it would bite me in the ass. The extremely bright "dark side" in the OP isn't entirely due to planetshine, but because the image had been doctored to hugely increase the brightness of that side of the moon. Planetshine isn't THAT bright.

Pretty sure I detect some light being reflected there...
>>
>>8750881
OK, fair enough. In summary, planetshine lights the otherwise dark portion of Mimas in the image, making them visible though still darker than the sun side; the dark portions have brightened artificially compared to the bright side, for purposes of making a full, clear image.

Pretty much. Planetshine is still there in the 2nd image I posted (otherwise the dark side would be completely black).

I was surprised that I seemed to be the first person to actually bother opening the link to see the info that it had been brightened after how long the thread was up.

>>8749750
Yet we still cant get close ups of earth from outside our own orbit

We cant get photos of jupiter when juno is right next to it

We cant point hubble at any of our planets and get crisp hd photos

Why does no ever ask these questions
>>
>>8749750
I guess it's because of the texture. Mimas is pretty homogenous, so it feels like a simple textured CGI.
It also seems very smooth.
>>
>>8749809
This is correct.
>>
>>8750778
>what are clouds

not all reflections are specular reflections anon

but Juno has sent back images already anon

its camera may be shit but the photos exist

also here's an image of Earth taken from ~1 million km
