Okay, where to begin?
With this paper, I want to demonstrate that we are probably living in the most important century for the humankind, as (and this is not only a strong intuition) there’s no doubt in my mind that the final proof of extraterrestrial life will be found within the century.
1- EXTRASOLAR PLANETS DETECTION HISTORY
2- EARTH-LIKE PLANETS
3- EXOPLANETS IN THE HABITABLE ZONE OF THEIR STAR
Since the launch of Kepler in 2009, the scientists have doubled the number of known exoplanets smaller than the size of Neptune. A hundred are smaller than 1.2 times the size of the Earth and even 21 are twice this same size, in the habitable zone of their star.
Nine of these have been validated (2016, May) and are plotted as orange disks in the map below. The previous known planets are marked as blue disks.
