Question: how do we know where (what direction, orientation, velocity) neutrinos come from? (lemmy.world)

I've seen a few articles about neutrinos recently, high energy ones, super fast ones, ones from open space, others from "sources", and my understanding of the particle is that it's very hard to detect, passes through light-years of lead without interaction, etc. don't headings and speed require multiple readings to make? How do we know the velocity of a neutrino when we can only detect them at single points?

There are two detectors, on opposite sides of the earth. Neutrino hits one, than the other.
