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?

Trouble with that is that the chance of a neutrino having more than one interaction in a detector are almost 0. And there could be detections from all kinds of directions.
