Lunar exploration continues to accelerate, and there's a new longest "structure" in the universe. Quipu is a quasi-alignment of clusters of galaxies stretching over 1 billion light years. Structure is in cynical quotation marks because these objects are not bound or connected to each other in any way, but their arrangement is a natural consequence of the evolution of the universe. If we happen to be in a Quipu-like structure ourselves, that may help us get out of our Hubble tension problem. Join us for cosmological mind-benders like this, and updates on ocean worlds and other moons closer to home, as well as space news and trivia.
