Some pics from mid-April of my take on Eris:
I tried going for some sort of mix between Ganymede and Pluto, hence the dark patches and cellular granules. I think it turned out nice.

Pluto and Charon

just a ice world and a gasgiant

two images of a mars like exo-planet

Solar System portrait

Bored, so here's some random screenshots:

Hurricanes Idalia and Franklin around the time of their peak intensities.

It's impressive. How did you add this to Celestia?

I did read up about hurricane models being made long ago, but none of them were published besides Katrina, which can nowadays be found in the Celestia ED addon of the inner solar system via: http://www.celestiamotherlode.net/addon/addon_875.html
Modifying was the only way to this day unless the other models were published and remained.

A nice conjunction of Jupiter and Uranus in 30th September 2498, seen from 67P/Churyumov-Gerasimenko
(I created a JPL Horizons .xyzv trajectory for it from 1600 to 2500, so it's a great coincidence that it happens about 1.5 years before the end of the trajectory)

Description of the left view:
The brown-white sphere on the left is Jupiter, the small object next to it is Europa, the bright dot on the right is Uranus and the object above Uranus is Io.
Description of the right view:
The bright spot is Jupiter and Uranus.

Note: The bluish background is caused by the tail of 67P.

The cel:// URL for the view (it doesn't need my 67P .xyzv because the observer is following nothing (free float)):

My artistic impression of what Proxima b would look like:

Tracking V380 Ori

VY Canis Majoris and WOH G 64.
The top 2 largest stars we may have ever discovered.

Each pixel in these screenshots is equal to Sol’s width in the 1,920x1,037 px resolution.
A width of 1,500 px in these highlights the maximum theoretical sustained size for a star in our current theory of stellar evolution (which’s around 1,500 x that of Sol).

The field of view was modified to minimize angular distortion by their 3-dimensional shapes regarding distance.

If either one of these stars replaced Sol, then per their calculations, their photospheres would engulf the orbit of Jupiter.

Dust clouds enshroud both stars.

Pi1 Gruis is a binary star system containing a red giant and main sequence yellow dwarf star.
The primary companion has a spectral type of S5.
The secondary companion has a spectral type of G0V.
The field of view was modified to minimize angular distortion by their 3-dimensional shapes regarding distance.
1 pixel on each image is Sol's width.

On this day, 50 years ago, Pioneer 10 became the first spacecraft to enter the outer solar system, and explore the planet Jupiter.

Like with the 40th anniversary of Voyager 2's Saturnian encounter, I decided to take this screenshot for the 50th anniversary of Pioneer 10's flyby of Jupiter.

A solar eclipse in Celestia:



Edited to make atmosphere/sky darker as Celestia does not calculate the effects of this kind of shadows in atmospheres:



Proof that the sun is really in Celestia and not just an overlayed eclipse image:



Maybe I will create an addon soon which allows you to add this sun to your Celestia (it is actually an addon right now but a private one and it needs some perfections ...).

There was a solar eclipse 3 years and 1 day ago (14 Dec. 2020). I posted this 3 years and 1 day later by coincidence lol. I did not even think about the eclipse in 2020.

So, because I was curios on what would happen when I set the options in Celestia 1.7.0 sRGB's celestia.cfg file like the ones below:



..., I found out that this makes Celestia look really weird:





Everything gets distorted as circle around a point somewhere near the bottom of the view.

This is really the weirdest thing I have ever found out in Celestia, I could not even imagine this before.

This is a projection for use on planetarium domes. See this thread where it was implemented.

Oh ok, but it still looks funny on normal monitors.

A view of Saturn from one of it's outer moons, Ymir:

Saturn is eclipsing the sun on Ymir (solar eclipse) and Ymir is being eclipsed by Saturn (lunar eclipse).
