OK, check this out.

Astronomers (not known for working in a dangerous profession), are getting knocked off, or rather they are suffering "accidents".

Quite obviously they are observing something, which either they're not meant to, or have refused to keep quiet about something, at which point they are silenced.



Couple of points :-
This is not a Niribu thread, I'm making no claims as to what they are observing.

Some of the astronomers covered are old, and could quite easily have just died of old age, others covered aren't old, 37 is the youngest.
