Observations from the most recent eclipse, which began in 2009, suggest a binary system made of a dying star and another star that’s surrounded by a giant disk of material. Yet despite figuring out what’s there, it leaves the question of why.
The disk in question is made of gravel-sized particles. It’s the sort of debris field normally found in much younger star systems. The recent observations were crowdsourced as part of a citizen science project. There may be enough information in them to figure it out—or we may have to wait another few decades.
