If a Neutron star, were to set off an emmision of Neutrons at us - we’d be dead, and never know what hit us.

I don't believe neutron stars emit neutrons, rather, that they are made up of neutrons. Though gamma rays would fit your point just as well - they hit us, we're toast, while looking around at each other saying "what"?

Aren’t Gamma rays, just directed streams of Neutrons?
