What I said before was about the GAIA DR2 database which's unreliable due to too much noise.
The GAIA EDR3 database on the other hand has noiseless data, making the observations much more reliable.
Sorry if I confused you.

I know it's been a long time since I posted here, and I know that might count as necroposting, but as this's the only board this news post is appropriate for, I feel like I have no choice but to post here. Recently, the GAIA EDR3 telescope has given us observations based on noiseless data that UY Sc...

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 Mo...

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

I didn't say the model was perfectly spherical (which's impossible for a poly model anyway), I just said it can use as much as 2 more subdivision levels to make a great appearance for simulating planets and moons. And I wasn't trying to promote a personal attack either, but I just wanted to point ou...

While as you said there are no perfections when it comes to making a "sphere" on stuff like Celestia, or common computer software (due to the poly nature and generally computer images being made up of pixels), there is the matter of what looks excellent even from a close up vantage point (...

Well SevenSpheres' showed me a link to this to reply after my honest review on the Celestia GitHub site about the emissive models on GurrenLagann's addons.https://github.com/CelestiaProject/Celestia/discussions/1882

Thanks for the info.
There's always something to discover.

Not to be critical or anything, but the poly resolution looks anything but excellent. The cmod models are 2 subdivision levels shy of being excellent in for planetary modeling. Though they're better than cmod models that are even just 1 subdivision level lower. Though this subdivision level looks go...

Some of the other versions of 55 Cancri A showed more reasonable depictions of e. The best depiction then was a dark world with lava fissures, as shown in SevenSpheres' addon. https://celestiaproject.space/forum/viewtopic.php?f=23&t=19978&p=150298&hilit=55+cancri#p150298 Though you did g...

In the Orion's Arm addons, the Arcadia addon included a 3DS mesh of it that only accounted for one time period and was unrealistic. I worked on Blender and made improvements of it with a UV "sphere" of twice the resolution (4x the number of faces), UV mapped the texture onto the mesh, and ...

Yes, and that the earth_to_scale.cmod mesh should've had its oblateness at 0 instead of 0.01 so that you can give it its own oblateness in the Celestia folder and have it and the atmosphere match up. No one wants to see an Earth mesh with an oblateness greater than its atmosphere, as that's too unre...

It's been quite a while since I was last active here. In the Rosette Nebula, out of all the known stars that were calculated, some show radii larger than any star we ever found and measured. For example, stars like HIP 500034 show radii of 2,700 X Sol's. And others like HIP 500053 show radii of 3,10...

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 ...

ok good to know.

Where's this?

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...

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

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