Amazing pictures! Also crazy to think about thr sheer size of space objects. This galaxy is 100,000 light years across. Mind boggling huge. The ring is made of "dust" and hydrogen, but that is only a generalization. I always laugh when scifi claims "aliens came to earth to steal our resources!" But then then you look at a picture like this and realize their are clouds that just float in space with more resources than our planet a million times over.
