Some time ago it was speculating that the emissary of the planet Earth on the red planet called Mars, the Curiosity that had been discovered signs of the existence of life on the Red Planet more known as Mars. At the end of the day, it has happened that the evidences that were ayeadas were not sufficiently esaptas to assure or to deny that there may be presence of some organic molecules in the Martian soil. And as you can tell, what can not be fully demonstrated through science is not a fact, but rather a speculation.
Although you can reduce the chances of life on another planet such as Mars, the speculation that there is awakened many old debate of this case: could it be possible that there is life on some other planets?
So far what is said, by expert voices in this great subject had been allowed to be skeptical about it, but for now the possibility of finding life on some other planets outside the earth and within the solar system is still growing, a say of the community that seizes all the scientists. And it is not only that, but reasons are emigrated for their justification that is renewed by their optimism for the possibility of finding extraterrestrial life on another planet and even on Mars.
The extremophiles that abound on the planet Earth are those organisms that have the posivilidad to be able to live in living conditions, usually, it can not be viable: as it can be the volcanic heat, the inevitable lack of oxygen, also the conditions of extreme pressure and to the void in space (these so-called tardigrades are those microscopic organisms that can only survive there). or rather, there are life forms that can prevail in conditions similar to those found in other different planets and the moons of our solar system.

These so-called molecules, after their evolution can even form complex chains like DNA, because they have their origin in organic compounds such as proteins, carbohydrates and lipids that were originally in the atmosphere and the sea. Well also: there is much evidence of the presence of these precursors in other worlds or rather in other planets. as for example Titan has some in its atmosphere and the spectrograph
reveals some presence of others in the Orion Nebula. Maybe they are not accurate evidence that aya life, but there is its possibility outside our planet earth.
It may be that in the last few decades, many or hundreds of extrasolar planets have been discovered (most of them are giants, gaseous, like the planet Jupiter). The exciting thing about this is that many are also very small planets that are rocky, like the planet Earth. Several of these are at a similar distance from their stars, than we are to our sun, which could produce in these a temperature similar to those of the planet Earth where we live.
