Revolutionary discovering thousands of candidates to exoplanets by Kepler mission (NASA) (http://www.nasa.gov/mission_pages/kepler) and their statistical analysis (e. g., Swift et al., 2013, ApJ, 764, 105) show that in our Galaxy are minimum of 100 billions of exoplanets from which 17-20 billions may be of the terrestrial size. These results are trustworthy for the following two reasons. The first one is arbitrary selected direction of Kepler’s telescope search in the Galaxy. The second is that the majority of the candidates to exoplanets belongs to systems of M-type stars which account for ~70% of the total stellar population of the Galaxy and Universe because of a large age of the stars caused by slow thermonuclear reactions in their interiors. The results considerably change our ideas about the surrounding world. The huge number of exoplanets immeasurably increases likelihood of exolife. At the same time, it seems extremely unlikely a transfer of living forms of life at a microbial level between different stellar systems under non-relativistic velocities. This is due to tremendous distances and hard space conditions. The emergence of our primitive life was going to happen either on the proto-Earth or within the early Solar system. We have pointed out (Busarev et al., 2003, EM&P, 92, 345; Busarev, 2012, ACM, 6017) on favorable conditions for such event in interiors of rock-ice bodies during their early thermal evolution and water-differentiation owing to 26Al and other short-living isotopes decay. Temperatures in the accumulated nuclei (similar in content to carbonaceous chondrites) of such large objects (>200 km) could reach hundreds of degrees for millions of years. The water-differentiated bodies from the growth zone of proto-Jupiter could be thrown out and dispersed everywhere in the Solar system and their matter might have been delivered at collisions to asteroids and other bodies including the proto-Earth (Safronov, 1979; Busarev, 2004, LPSC-35, 1026; Busarev, 2012, ACM, 6017). Results of Kepler mission make a new look on the problem of a hidden mass in the Universe. If the mass is concentrated in the invisible dwarf stars (brown, black, and others) and planets, it could not be less or even more than the total mass of the M-type stars. If it is so, the invisible or dark mass of the Universe may reach ~50% of its total mass. As follows from this, the discovered accelerated expansion of the Universe can be provoked by external gravitational fields and not by internal dark energy which is endowed with the property of antigravity.
