The first time I saw this photo at the European Space Agency's XMM-Newton space telescope site I couldn't believe my eyes. It didn't look like any space structure I've seen before. It actually look like some kind of weird inter-dimensional portal.
I'll give you a hint: It came straight from a human mouth.
It looks like some kind of a computer-generated subatomic particle visualization, but no. In fact, this thing is huge, and very tangible. You can even get inside.
