The Master Plan, part I
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.

Alien call I.
First contact will probably - if it ever takes place - not be face to face, instead, a distant call may be radioed purposefully or not. Neither will it be a true dialogue unless some fundamental physics breakthrough emerges. For decades now, many people are scanning the dial looking for signals. You may help too.

OUR black hole. Part II
