The majority shoot right through the Earth as though it isn't even there, making them exceptionally difficult to detect and study.Despite this, researchers have worked out that many are created by the Sun and even in our own atmosphere. But the source of one high energy group, known as cosmic neutrinos, has remained particularly elusive.Now, in the first discovery of its kind, it turns out that a distant galaxy powered by a supermassive black hole may be shooting a beam of these cosmic neutrinos...
