Re: history of Earth

The problem with the earth_to_scale.cmod mesh is that its oblateness is MUCH greater than that of the actual Earth is. Earth has an oblateness of 0.0033528 and the mesh (which was made in 2006) was made with an oblateness of 0.01. The model should've originally been made with an oblateness of 0, so ...

Re: Spacecrafts for Celestia

Creating a surface object is more complicated than people realize. It takes not only exact location, but also exact orientation of the model and these kinds of addons are pretty rare as far as I know. The Deep Space Network is a worldwide constellation of radio telescopes including those in the Unit...

Re: Spacecrafts for Celestia

Since the SSC file isn't included, it's useless.

Re: Project Sisyphus - Texturing/painting every exoplanet known

These are great textures, though there's also an addon about pulsar planets and they include auroras on these planets.

For sure. CZ Hydrae Using nessun's RSG addon https://celestia.space/forum/viewtopic.php?f=6&t=20398 for realism. CZ Hydrae, an M-type red supergiant located in the constellation Hydrus. It's located 560 ly from Sol and estimated to be 986 x Sol's radius and is one of the coolest stars known to m...

Re: IC 1101

Well, you're right on that one. While I don't know a lot of examples, I do notice Antares as having a bigger radius than Betelgeuse, whereas in reality, Antares is slightly smaller than Betelgeuse. Also without putting the Largest Stars database, the size of Mu Cephi is at an impossible 3900 radi! ...

Re: Shape of the Milky Way updated based in Robert Hurt's Concept

This's a big improvement for the Milky Way model.
It even shows the darkness on it when you're in the arms, as if there was dust.
It totally beats the default model any day.

Re: Spacecrafts for Celestia

Remember all bodies have mass and that causes gravity and the gravitational pull of Sol and the other bodies gradually precess the orbits of moons. Even the planets themselves are affected though also gradually. Plus think about the gravitational resonances that happen when planets pass by 1 and ano...

Of course, credit is what's needed, and it makes more than perfect sense.
It's logical.

I used this merged texture: https://www.planetary.org/space-images/merged-cassini-and-juno Added after 1 minute 44 seconds: City of Rome from BlenderGIS: This should be considered as a release in the future, though it needs to work on Earth with its oblateness used.

I know, and if you have it on, then you would see it unless the stellar magnitude you have set is too low.

The visibility of the Oort Cloud depends on what magnitude you have Celestia set on.
If you click the ] it increases the magnitude and the [ decreases it.
