The NASA laboratory confirms that DNA sugar can be made in space, adding evidence that life & # 39; be across the universe

NASA researchers in Ams Astrophysics and Astrochemistry Lab in Mountain View, California have provided the first experimental evidence that shows that the DNA-2-deoxyribose sugar can be formed in a space between -estel. In their study published on December 18, 2018 in the magazine Nature Communication, Michel Nuevo, George Cooper, and Scott Sandford combine organic compounds, water vapor, and light – all the elements present in interconnection space – inside a vacuum chamber highlighting the cosmic environment and observing the results. Along with DNA sugar, it has been found that a variety of other sugar derivatives have been created. This finding is more evidence that chemical building blocks could be common over the universe, seeding other planets as the Earth did in the ancient past.

One of the most frequently asked questions quizzes is always one of us in the universe, a research effort that takes many paths . Carl Sagan's amphitheater is often quoted as saying, "Our nitrogen is our DNA, the calcium in our teeth, the iron in our blood, the carbon is made our apple pastels in the fall of stars. We're made of star things. "It meant that the universe was full of building blocks, so the effort to discover how these building blocks are Combining to form life really strives with the implications to reach further. Scott Sandford, a study researcher to this, referred to his own team's experiment, saying, "The universe is an organic pharmacy. It has a big bike and a lot of time – and it's The result is a lot of organic material, some of which are useful to life. "

To make their discovery, the Ames team cooled an aluminum substance to an absolute zero inside a vacuum chamber (as space is empty), and adds a mixture of water vapor and methanol gas before exposing to light and ultraviolet heat, abolish a completely warlike environment. The space between the stars is filled with dust and gases and is consistently taken to light particles that are pumped in from all sources that emit radiation from & # 39; i around. The experiment was designed to help answer the question that the space environment itself can make the compounds essential to life rather than just the one-elemental construction blocks. Another team of French researchers discovered the formation of ribose – the sugar in RNA, a potential predecessor to DNA – in a similar experiment to the current study, setting the platform for the team's further findings.

An increasing number of organic compounds have been found on meteorites over the years, including carbon, hydrogen, oxygen, nitrogen and sulfur. Despite the geography that is actively changing in the Earth compiles discovering traces of very early days, scientists have been able to find things like carbonaceous chondrites, asteroids derived asteroids as soon as the solar system. This research has made it possible to analyze how planets have formed and developed over millions of years. Combining this type of research together with other work showing that the meteorites generally include building and ride blocks throughout galaxies and universe, the number could expand from exoplanets found to suggest even more significant possibilities.

Exoplanets, that is, planets that are other orbit stars other than ourselves, are routinely discovered as data from observation observation and previous telescope and are currently being reviewed. Over the past 20 years since "hela planed" started, over 3800 exoplanets have been confirmed with around 2900 more expecting confirmation. By observing how much light a star star is doing over a period of time, scientists can determine whether a planet is overlapped, its size, distance from star, and missing colors are spectrum The planet's light atmosphere that says what chemicals are present, such as oxygen, carbon dioxide, nitrogen, and so on. After analyzing all these things, it can be anticipated that an exoplanet can be similar to the Earth and is what is known as a "Goldilocks Domain", or a situation in which life can be we know that he has the right conditions to evolve.

That may seem as many conditions to meet, but it is estimated that about 20-50 percent of stars in our nightstore will have small, rocky planets in the zones that are # 39; n live in their stars As more is learned about the formation of a planet, that number can be modified up or down. So far, one planetary system has a vast amount of study with little planets similar to Earth: TRAPPIST-1. It features a super-cold dwarf star with 7 rocky cliffs covered, all of which can get water, slightly more than Earth. Taking into account the growing evidence that the seeds for life develop are distributed and clearly created through space with many potential Earth planets being discovered, we may have some exciting news of the war world in the near future.
