Bumped into a youtube publisher, sixty symbols, that seems to be astronomy and physics, from University of Nottingham. The two I watched were about (a) the largest so far discovered galaxy, and (b) more intriguing, a structure that seems to be the largest in the universe. A string of quasars 4 billion light year long. What makes it especially interesting is that this would be too big for a homogeneous universe.
