Life comes from space

The initial theory of the origin of life on Earth, which was based on the simple idea that life formed on Earth from own resources to the primitive planet, is outdated. From there, environmental conditions and climate have encouraged the formation of compounds increasingly complex, the famous bricks of life.
At its discharge, this theory was formulated while our knowledge of the universe were more limited. They tended to make us understand that complex molecules at the base of living could not survive in space. But in recent years significant progress has been made. In terrestrial laboratories, first, where researchers were able to simulate the primitive environment of the Earth and better understand the conditions that prevailed in the Solar System then recently formed. In space telescopes and then where probes cometary we have opened a new window on the origins of life. The theory of panspermia itself then as inevitable.

The theory of Panspermie
The theory of panspermia suggests that life comes from outer space. Landed in the heart of meteorites and comets, the ingredients of primitive life could have then crossed the Earth's atmosphere without suffering damage and have seeded Earth somehow.

In scrutinizing space, exobiologistes have discovered that all the ingredients of life there. The clay, water and complex molecules, everything is there. The hydrated silicates micrometeoroids and other comets provide water oceans land, where their species and their volatile organic compounds inevitably trigger a prebiotic chemistry.
Better still, recent data show that an intake of extraterrestrial materials hydrated carbon-million during the years that followed the formation of the planet has probably led a surprising diversity of reactions to prebiotic chemistry to finally bring macromolecules gifted properties functional life (transfers of information and catalyses) to organize. We know the result.

The comet Tempel-1
More than 2 years after the collision waged against the comet Tempel-1, a study of the analysis of its nucleus and éjectas that followed confirm that life has good space, so that the Earth could have been seeded with particles containing celestial beings, cosmozoaires. This is the conclusion reached by a professor at the university right in line with the theory known as panspermia joining the results of the probe Stardust, which was discovered inside of the comet Wild 2 a range of complex molecules hydrocarbons, which is assumed to be ingredients of primitive life.
The scientist in question has discovered a mixture of organic particles and clay inside of Tempel-1. However, one of the theories used to explain the origins of life based on clay particles that have acted as a catalyst, converting simple molecules into complex structures. The team of scientists also suggests that radioactive elements can maintain water in its liquid form inside the nuclei of comets and for millions of years. Indeed we can talk about ideal incubator for organizations of primitive life. The billions of comets in our Solar System and the Milky Way contain more clay that the primitive Earth was able to contain.

The origin of life
The theory of panspermia does not provide answers about the origin of life. It only push the mystery of the origins of life, moving from Earth to space. If life is born with the universe, and it has always existed, it explains its presence on Earth, without solving the problem of its appearance in the Universe.
But the emergence of life is an extremely complex process that can not be summed up in a few lines. Each stage of life is a challenge to exobiologistes. For now, the explanation for this coming too often relies on theories than on concrete observations.
