Wow, have you been finding these yourself Xsannz? Just curious to know how common a find they are. It’s good to know that their not limited to just the Pleiades nebula, but perhaps just the Pleiades region? (and I heard chatter of typically vague Mike Brookes talk of one other region where they may occur? I haven’t seen the source on this though).
I just had a thought. We are flying around in space “ships” after all. Perhaps soon we’ll be scraping worthless barnacles off our hulls every time we return from an exploration voyage. They could become a galactic menace.
