Celestia now uses the TASS 1.7 theory to simulate the orbits of the Saturnian satellites. This model provides increased accuracy many thousands of years into the past and future. #space #astronomy #OpenGL #opensource #simulator #planetarium #CelestiaProject

At the highest settings, this Dell laptop (i5-1335U) runs Celestia with the new atmosphere renderer at 45-60 FPS, and lowering the settings increases performance with a minimal loss in quality. #space #computergraphics #rendering #OpenGL #opensource #simulator #planetarium #CelestiaProject

WIP new atmosphere parameters for Triton and Pluto. Very tenuous atmospheres, you might not even see them on your screen, so I've included a screenshot with an increased exposure as well. #space #computergraphics #rendering #OpenGL #opensource #simulator #planetarium #CelestiaProject

Wrap lighting can be used to fix an error with cloud rendering around the terminator of an object. Here is what that looks like with Titan, and a real photo of Titan for comparison. #space #computergraphics #rendering #OpenGL #opensource #simulator #planetarium #CelestiaProject

Cloudless #Venus. In absence of any gases absorbing visible light or aerosols blocking the path, Rayleigh scattering in a sufficiently deep atmosphere would be able to fully scatter all light back, producing a white planet. #CelestiaProject #astronomy #space #planet

Hello, Bluesky. We are reworking planet atmospheres in @celestiaproject.bsky.social after a major, long-awaited atmosphere rendering bug fix (mentioned in that account). #Celestia #CelestiaProject #space #planet #Earth

Improvements have been implemented. In the third image, Titan's atmosphere has a much softer edge, this is achieved by simply lowering the AtmosphereExtinctionThreshold in the source code. #space #simulator #computergraphics #rendering #OpenGL #opensource #CelestiaProject

By using the Chapman function, scattering can be made more realistic, especially for tall atmospheres. Here's what that looks like with Titan. Not final, subject to change. #space #simulator #computergraphics #rendering #OpenGL #opensource #CelestiaProject

Earth's atmosphere has been overhauled using data from various studies, and true colour images as a reference. The same has also been done for Venus, Mars, Titan and Pluto. #space #simulator #computergraphics #rendering #OpenGL #opensource #CelestiaProject

Ten years of hide-and-seek! 🫣 Astronomers used our VLT to find a new #exoplanet orbiting the famous star Beta Pictoris — hiding in archival ESO observations spanning over a decade! And it's shyer than any exoplanet we've imaged before. 🔭 🧪 1/3 📷 ESO/B. Sutlieff, M. Bonse et al.

Now that sRGB rendering has been added, we can revert the Earth's atmosphere parameters back to the ones used before 1.7.0, making it more accurate to true colour photos of Earth. Views from the surface also look better. #space #computergraphics #rendering #OpenGL #opensource #CelestiaProject

No less than 60 million stars in one image. It's possible thanks to ESA's Euclid mission. For just one day, Euclid turned its gaze to the crowded heart of the Milky Way and captured the largest, most detailed photo ever taken of our galaxy's centre in visible light. Let's dive deeper 👇 🔭 🧪 ☄️ 1/8

The account has been suspended! Don't know why because I only had delegate access to the account, wasn't under my email. This is unfortunate but it does give me the opportunity to create a new account under my email that I can have full control over.

Twitter has restricted the account for a reason that I can't find out and now I can't tweet anything. Amazing!
