Artifacts Under 1.55.376713.1

I just started a new game as the Yor under 1.55.376713.1 and I noticed 2 Artifacts near my home world.  However, if you look closely at the 2 Artifacts, the icons are slightly different (see the screen snapshot below).  When you hover over them, they both show the same popup describing them as Artifacts.  Are the different icons supposed to convey information about the types of artifacts that they are?  If so, shouldn't the popups be different?  If not, why the different icons?
