The NASA lab can place DNA in the cosmos and prove that life is all over the universe.


NASA researchers at the Ames Astrophysics and Astrochemistry Lab in Mountain View, California, have presented the first experimental evidence showing that sugars in DNA-2-deoxyribose can occur in the interstellar space. On December 18, 2018, published in the magazine Nature Communications, Michel Nuevo, George Cooper and Scott Sandford, combined with the combination of organic compounds, water vapor and all the light elements – inside a vacuum camera that imitates the cosmic environment and its results. In addition to sugar diet, various sugars have also been created. This discovery is more evident that the chemical structure of life can be spread throughout the universe, and in the ancient past, other planets like the Earth are scattered.

One of the greatest questions is the persistence of science, the only one in the universe that we are the only one who searches for a long time. Astrophysicist Carl Sagan is often referred to as: "The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the apple-free carbon in the collapsing stars, we were prepared from the stars." This means that the universe is full of life blocks, so it has far-reaching consequences to discover how blocks of blocks really work together to create life. Skot Sandford, one of the researchers of the study, referring to his team experience adds: "The universe is an organic chemist, very beakers and often have the result – a very organic material, and some are useful for life."

To explore, Ames has added a water vapor and a methanol gaseous mixture to an ultraviolet light and heat before an aluminum substance has cooled its absolute zero to the zero (since space is empty) and the interstellar medium. The space between the stars is filled with dust and gases and is constantly exposed to the bombardment-resistant light particles from the radiating sources around them. It is designed to answer the question of whether the experimental cosmic environment can make compounds that are essential for life than single elementary blocks. A group of researchers in France discovered the formation of sugars – ribose in the RNA – a trial similar to the one used earlier by the group for more findings.

Several organic compounds that have been growing in meteorites for years, including carbon, hydrogen, oxygen, nitrogen and sulfur have been discovered. Despite the active geographical location of the earth, scientists from the earliest days discovered and learned about obsolete things like carbonized chondrites, planetary meteorites, and our solar system. This study has allowed billions of years to analyze how the planets are shaped and developed. Combining these types of research suggests that meteorites generally cover life and travel blocks throughout the universe's galaxies and that are more important to the extensibility of existing exoplanets.

Exoplanets, i.e. planets with other orbit stars, are discovered on a regular basis because the data of the previous and current observatory and telescopic missions are being studied. Since the "Planet Hunt" has actually started, over 2,800 expoplanets have been confirmed over the past 20 years, more than 2,800 confirmed. By observing the light of a distant star, it can determine whether a planet extending over time, its size, the distance from the star and the color in the planets is an atmosphere that tells them what chemicals are. oxygen, carbon dioxide, nitrogen and others. After analyzing all of this, you can estimate that the exoplanet is like the Earth and that it is called the "Goldilocks Zone" or that it can have the right conditions for the development of life we ​​know.

It may seem like a lot of point of view, but about 20-50% of the stars in the night sky is estimated to have small, rocky planets in their habitable zones. This figure can be adjusted up or down as more information is available on the formation of the planet. To date, a planet system has been widely studied, with some similar planets to the planet: TRAPPIST-1. It consists of an ultra-cool dwarf star with seven orbiting stars, all potentially water and more. Taking into consideration the evolution of the seeds for the development of life, potentially in space, the possibility of the creation of the planet is widespread and created, and in the near future there may be some interesting news from the interplanetary world.
