I was surface prospecting when I noticed a strange dust phenomenon on the horizon. I thought maybe it was a star matching the same intense orange-red of the planet I was on, coming over the horizon. But the only one I could find was a dwarf star and it illuminates with a dulled purple/maroon shade and is in another area of the system. The main star is directly above me on a tidal-locked planet (or its orbit is very, very slow). The odd phenomenon wasn't there for long, though. Wishing I could have nabbed a screenshot of it. Anyone else seen this? Any idea what it could be?
