Comet bombs life bombs on Earth

The impact of comets fired on Earth may be the agent that helps form protein and lay the foundation for the life of the green planet.

Previously, scientists learned that comets are the agents of "transporting" organic chemicals and water to the early Earth. However, what makes life - which does not form anywhere else on billions of planets in the universe - that grows on Earth is always a mystery.

Comets provide all the materials needed to form life.

Now, researchers believe they have found a part of the answer. Laboratory tests have shown that the amio acids - the organic cells that make up proteins - may have survived extremely strong pulses caused by comets. More amazingly, they are also provided with the energy needed to begin to bind together and create protein cells. In turn, protein is the premise raw material source of all living organisms, from bacteria to humans, that can exist and function.

It is the catalytic role of comets that will explain why resurrection appears so quickly at the end of the earth's period of "intense bombardment" 3.8 billion years ago. At this stage, the Earth is constantly in the sights of both comets and meteorites, the traces left to this day are the concave deep holes on the Moon's surface.

Share on DailyMail, Dr. Jennifer Blank of NASA / Ames Research Center (California, USA) said, 'Comet is the ideal cargo ship to supply materials for the evolution of chemical origin, so life. There are all the ingredients we need in comets: amino acids, water and energy. '

Dr Blank's research group has just been presented at the annual meeting of the American Chemical Society. Accordingly, they recreated the Earth's condition 3.5 billion years ago when the Earth was constantly being hit by comets. Many comets have a diameter of up to 10 miles or more.
