In addition to small boxy bulges, large spheroidal bulges, and pseudobulges, it is possible to identify one more type of bulge: a giant boxy bulge, often containing an X or Peanut shape. A good example of a giant boxy bulge is that of NGC 128:

And wow, we've just found out our galaxy is peanut shaped too

Reading what you said about those pseudo bulges was fascinating to me. I hadn't realised they existed until I saw the latest news on our galaxy.
So, in simple terms (if possible) what causes the peanut shape, re the disc matter (if I got that right?) falling inwards- do you know?
I'm sure you've seen it, but I'll pop it up anyway, this is the new pic of our milky way galaxy showing that X/peanut shape.
