Ray Jayawardhana: It is a clue that most likely, these high energy neutrinos come either from jets of particles that are accelerated by super massive black holes at the hearts of galaxies, or from really gigantic stars that explode at the end of their lives that also produce a phenomenon we call gamma ray bursts, which also might accelerate particles to very high speeds and energies.

Even protostars — these are young stars that are just forming and making their own planetary disks and so on — they make very powerful outflows called, the same sort of jets obviously moving at slower speeds, but they are full of plasma, that is flowing out at high speed; white dwarfs, neutron stars, black holes big and small, they seem able to do this task, it really seems to be a very common phenomenon.
