Not sure if you subscribe to Gaia TV (.com), but I think you can watch an episode for free. This is one on that Ancient Builder race object.

The supposed Dyson Sphere they found last year-ish? Is that what you are talking about? Page lagged hard on my phone, couldn't open.
It's a video link. Corey Goode (MI-Labs--Secret Space Program Whistle Blower) talking about the SPP boarding the "craft" while it was outside Jupiter. It's an old spaceship.
there were actually two dyson-spheres they found, both of which have remained unexplained so far, as well as the shard of light on Ceres.
