Observations such as the Danish telescope in Chile was shown that the general rule is that stars are surrounded by planets, and there are an estimated 10 billion tillotama shome stars with planets in the habitable zone. By Jens Ramskov 11 2012 at. 19:00
This was stated by astronomer Uffe Grae Jorgensen of the Niels Bohr Institute tillotama shome at the University of Copenhagen in connection with the publication of a new article in Nature on planets that have been found by microlensing observations including the Danish telescope at La Silla Observatory in Chile.
He stresses, however, that the possibility of liquid water is not a guarantee that there are indeed life, like any life, in principle, can take quite different forms than what we know from our own planet.

The Danish telescope played a key role in the international Planet project to find exoplanets with gravitational microlenses.

In this situation, the gravitational field around the star closest to Earth seem like a lens compared to the light from the rear star. This can be more accurately than would otherwise be studying the variations in light intensity from the rear star, influenced by the planets shadows of the star's light.
Using these measurements, the researchers in the plane project has been able to make a statistical analysis of how many stars that have planets that are located at a distance of between a half and ten astronomical units (an astronomical unit is equal to the distance between tillotama shome the Earth and the Sun, which is 150 million. miles.)
Analysis tillotama shome shows that 17 percent of the stars will have planets in Jupiter-class (0.3-10 times Jupiter's mass), 52 percent will have planets in the Neptune-class (10-30 Earth masses), while 62 percent of the stars will to have planets with a mass of between five and ten times Earth's mass.

It's fairly certain now that habitable planets are common, but how do we go from here? The next step must be to discover life on a planet outside the ground, but it seems that there are many years before the technology can handle it, unfortunately.
Drake's equation, and various derevirater is the best bet for assessment of probability. Of figures magic does, in my opinion, it is quite clear that there is life in many places and at different stages.
Variants of the equation also speaks of "simultaneity" - which means that in addition to the geological conditions and the evolutionary assumptions, then also a diversity factor achieved. Our people may technically-developmentally called "developed" between 1900 and some hundred years - a window of 200 to 500 years. With the same goal. plus a propagation delay between planets with the speed of light (we assume), then the "contact" = "knowledge" in memory of "ships in the night".
But again, the big, vast, century magic makes it probably will happen. Just think that the jump from astronomers observing the "stars" to the current recognition of "galaxies" (which is 60 years old) - everywhere. Or the ability to identify tillotama shome extrasolar planets - which is just 10 years old.
We should put all our scientific resources into it, instead of going and fiddling with global warming, overpopulation and everything else, which is talking and talking and there is a stick.
I think "sorry" well I can promise you that when our sun in due course become a red giant, humanity is gone for very very very long time ago. Maybe replaced by something else, but it is futile to persuade oneself that we would survive more than maybe a few hundred thousand years. Until now says "odometer" of approx. 100,000 years, of which perhaps 50,000 which is really tillotama shome intelligent, 300 as having a proper technical civilization - and we've already been eerily close to obliterate ourselves.
And the technical difficulties by simply bringing a single spaceship to the nearest star - Proxima Centuari 3.6 light-years tillotama shome away - are such that, with our current technology is completely ruled out. And Proxima Centauri have any planets.
And technological advances can not do it, the much talked barrier at the shelter
