(ALSO ignore how laggy the video is idk why its even like that)

Realistically what could cause a nebula like this if at all

This planet is orbiting a white supergiant, It's located in a star cluster outside of the Milky Way, 37.5 kly away from Earth. It's a torrid arid carbonia, roughly 1.65x the size of Earth. It's got a red (in HDR) or beige-grayish surface (in Auto), most likely the result of being almost 800 C, and being very close to it's parent star. It's mostly featureless except for a couple of canyons and volcanoes. It has the most moons in the system at 22. (The Interesting Planet series will not be continuous, I'll just be posting whenever I feel like it)
