NASA MADE INGREDIENTS OF LIFE IN SPACE.

NASA scientists who are working at the AMES ASTROCHEMISTY LABORATORY in California and the Goddard Space Flight Center in Maryland have found a clue to the mystery. They came to know that some of the chemical components of our DNA can be produced in the harsh crucible of space.
They created a chunk of ice in their lab made from molecules known as pyrimidine. These molecules,consist carbon and nitrogen, they form the core of three chemicals found in our DNA and RNA, the genetic composition of all living things.
Pyrimidine is also found on meteorites, which encourage the researchers to further explore how it will react when frozen in water and in space.
They put their chunk of ice in a machine that recreates the vacuum of space, along with temperatures approx -430°F and harsh radiation created by high-energy ultraviolet (UV) photons from a hydrogen lamp a perfect space condition.
They found in their experiment that not only could the pyrimidine molecules survive these brutal conditions, but the radiation actually morphed some of them into three chemical components which are found in our DNA and RNA: uracil, cytosine and thymine.
christopher matarese, a NASA researcher working on these experiments, said that We are trying to address the mechanisms in space that are forming these molecules, he further added that Considering what we produced in the laboratory, the chemistry of ice exposed to ultraviolet radiation may be an important linking step between what goes on in space and what fell to Earth early in its development.

Scott standford, a space science researcher at Ames,said in his statement "Our experiments suggest that once the Earth formed, many of the building blocks of life were likely present from the beginning. Since we are simulating universal astrophysical conditions, the same is likely wherever planets are formed."
While this research might help to further know about our space. Scientists don't exactly know from where this meteoric pyrimidine comes from, although they theorize that it could arise when giant red stars die. we should wait and watch while the search for the treasure continues.
