With base the data received by the space telescope Hubble and the Kepler space observatory, a team of NASA scientists found that most habitable planets have not even been born yet.
In a nutshell, we say that of all the potentially habitable planets that will appear throughout the universe, only a handful have so far been formed. The majority of inhabitants planets is likely to form after the Earth is lost.
And they explain to us researchers from NASA.
"Our solar system was born 4,6 billion years ago and so far only 8% of potentially habitable planets have formed. The vast majority of these planets - that is, the remaining 92% - have not yet been born, ”NASA researchers explain.
As it seems, the existence of our planet is a rather premature arrival compared with the next arrivals expected in the entire universe.
But which planets can be described as habitable? They should be about the same size as the Earth and are in the so-called habitable zone from their sun, neither too far nor too close. Thus, they should be in an orbit, where conditions will allow water to form, in liquid form.
Then, if the planet is rocky, then there is an even greater chance that the existence of life forms, which from primitive could initially evolve.
And if we consider the numbers, the matter becomes more interesting. Scientists estimate that in galaxy there should be about 1 of us billion planets like Earth. With around 100 billion galaxies in the observable universe, it means there are a bunch of spheres similar to our cosmic home out there.
But again, scientists believe that all these celestial bodies represent only a delectable 8% of the planets to be formed throughout the history of the universe. They say there is enough leftover material [after the big bang] to produce even more planets in the future.
