Looking down the barrel
Gamma Ray Bursts (GRB's) puzzled astronomers for decades since their discovery by the Vela nuclear test surveillance satellites in the 60's. Scientists think now the mystery has been solved, adding yet another (unlikely) threat to the catastrophes lurking out there.

Space research may appear as a somewhat chaotic dispersion of disparate efforts, space probes, ground telescopes, space telescopes etc. Yet this is not completely true. Scientists manage to arrive to certain consensus, while politics has, the last say. First of a two part article, within a series of related installments.
