A study published recientemiente by scientists at the University of Nice Sophia Antipolis (Switzerland), has found that a substance of comets under the action of ultraviolet light can serve as a substrate for formation of ribose sugar.
& gt; & gt; Swiss explain how the mysterious planet-nine.
According to this work, ribose could be in space ice irradiated with ultraviolet light given off by comets, which form part of known interstellar dust that revolves around young stars.

Ribose is the essential RNA sugar. This molecule is the precursor of DNA, Without that element, human life as we know it could not exist.
The ribose sugar is formed when the ice of comets is under the influence of ultraviolet radiation explains the research.
To test whether ultraviolet radiation causes these photochemical reactions, the process has been reproduced in the laboratory at a temperature of about 200 degrees Celsius in a vacuum. Water, methane and ammonia (the components of the substance of comets) were deposited on the surface supercooled with a ratio of 10: 3.5: 1 and then exposed to ultraviolet light.
Scientists then raised the temperature to the ambient level. As a result of the experiment organic substances as ribose and arabinose, xylose, lyxose and other complex compounds formed.
Thanks to this research it is possible that human life on Earth may have arisen thanks to comets.
