Seems like merging galaxies. It’s too far away to be a single star being eaten by a companion. (It’d have the six-sided star mirror artifact if it were closer.) And galaxies temporarily form weird shapes as they merge

Just speculation but it would be totally plausible for a helix shaped galaxy or star (possibly being pulled into a black hole) oriented from an odd angle, with either a gap or a cloud of some sort blocking one part of it and it just happens to look like a common glyph.

But I’m no starologist
