I wonder if this could be a Stellarium plugin...

Skylight offers a planetarium experience since it doesn't just track the aircraft; it recreates the real sky behind them. The pure black ceiling background not only shows the illuminated aircraft but also displays the sun, moon, stars, and constellations, all rendered at their precise positions for your location and current time, along with live satellite tracking, including the International Space Station (ISS).

This is an incredibly cool way to replicate what you’d see if you just… stepped outside lmao
(Fr tho it’s a really interesting project)
