Some more things that happens in real life... The way stars, planets and moons are seen through a thick atmosphere. For example, the moon appear big seen from horizo, while it appears smaller when high in sky. My suggestion is to put a code or algoritm so that worlds seen from a thick atmosphere will suffer such effect. The more pressurized the air is, the stronger will be that effect of distortion of shape. And another thing, stars seen from an atmosphere shiny, they are not static as they appear in space engine, right? Ah, yes, there's another thing... fog.

The atmosphere code should have another algoritm for fog, independent from the model of the atmosphere.

Let's take Titan for example. In space engine the surface of Titan looks crystal clean, but it's known that the air of Titan is very foggy, in a way that it's difficult to see distant things from the surface. And that may be simple to make, it seems. So instead of having that odd cloud layer, it would have a new fog layer with some few clouds of methane. Because that opaque layer is not really a cloud, but a smog or something like that. The fog doesn't have to be volumetric, only the clouds. The more near the surface, the stronger should be the fog effect, for worlds that have more opaque atmospheres.

Another effect is that related to Venus, the high temperatures distort the shape of land. An algoritm for such effect should be implemented too, for hot planets or moons, specially with dense atmospheres. The higher the value, the stronger the effect, same for the fog effect and for the distortion of shape related to the size of worlds and stars seen from the horizon.

Fata morgana effect is also an advice too, specially for hot desert planets.

This is purely a psychological effect in the brain.  If you take a photograph of the Moon near the horizon and compare with another taken when it is high in sky, it is the exact same size.

The actual, physical effect of the atmosphere on celestial objects is to dim them and redden the color, which the current code does simulate.  There may also be a squished or distorted shape due to inversion layers in the atmosphere, and the change with density with height, but this is not currently simulated.

I know this, but Space Engine is supposed to show the universe the way we perceive it, not the way cameras perceve it. If not the way we perceive, then it's not so immersive.

If Space Engine showed the universe the way we perceive it, then galaxies and nebulae would look dim, desaturated, and boring.  You would also be blind before you could see the details in the surfaces of hot stars, or in the accretion disks of black holes and white dwarfs.  I think it is also better to show things the way they are, not as how we are tricked by illusions in the brain, or in the above examples, by limitations of our vision. :)

No, it's supposed to show the universe the way that it is. If SE showed everything 100% accurately, and we had perfect VR technology, then you would see the moon as looking bigger on the horizon without SE rendering it any differently. Because it's all in your head. Asking that SE replicate psychological effects and illusions makes no sense, because those are not part of the real universe. They exist only in the mind of the observer.

This is SpaceEngine, not PsychologyEngine.

Sorry guys but I am with enioquedes on this. I mean, I think SpaceEngine should eventually do it's best to get the brightness, lighting, and eye exposure as accurate as possible as perceived as us...AS AN OPTION. The current Auto exposure mode is kinda ok at this, except it doesn't have the limits that we have. 
Of course we are only simulating "brightness" with diffraction spikes, but when I play with Space Engine, especially in VR, lots of times I wonder how things really look, rather than how they are being shown to me. Most of the time I can do this, but not always. And obviously I am not talking about going blind, but I do think that things brighter than we can "adjust" to should definitely get completely washed out, and things dimmer than we can perceive should just be black in Auto mode.
As for the things that are illusions in our brain, well yeah, I agree that our brain would also do them in Space Engine if we had great VR and Space Engine was set up right

It looks like Björn Jónsson has created a new high resolution texture for Jupiter combining Cassini images with Juno data from polar regions.

If I'm correct this is currently the largest Jupiter realistic texture available right now So It would be interesting to add this to SE main addons maybe.

The previous texture was created only from Cassini data in 2005 and it's 2880x1440 pixels:

The new one just merged that with 65 km/pixel resolution polar views from Juno and oversampling the rest of the texture to accomodate that. This new image is 14400 x 7200 pixels in size.

More on that here. And to download the loseless new texture click here

I already integrateв this texture in SE. Also next Overview update will use it. its resolution is much greater, in Overview it has per-pixel quality in Vive and Rift.

Oh sorry. I wasn't sure. Good news :)
