And it was in the 18th century, astronomers went across the world to measure the entry and the exit time. And they could use that by kind of complicated triangulation to calculate the distance between Sun and Earth, which then became the yardstick to have the distances of the whole solar system. So it's the first scientific collaboration, and it's an extraordinary moment where in 1761, in the middle of the Seven Years War, you have hundreds of astronomers spreading out, working together, because they all have to share their different timing and then calculate, but only when they do it together."
