In 2012, a group of Japanese and Belgian scientists visited Antarctica. The team found something surprising, lying on the snow covering the continent in the shape of a golf ball sized meteorite. The meteorite was officially named & quot; Asuka 12236 & quot;, although it was quite small, < / P > < p > at the Goddard Space Flight Center, NASA scientists were finally able to access a small section of the original meteorite to process and decode the information in it. They processed a small portion of the meteorite with a pestle in the laboratory and suspended amino acids from the dust in aqueous solutions. They put the liquid into a machine that was designed to separate the molecules by mass and identify each molecule. < / P > < p > the team found that a lot of amino acids were locked in the interior of the meteorite. The concentration of the meteorite is twice that of the best preserved space rock of its kind, Paris. These molecules include aspartic acid and glutamic acid, two of the 20 amino acids that form their own arrangements to form proteins. These proteins are essential for life on earth. The researchers found that meteorites were full of what the team called left-handed amino acids, the precursors of life, which they thought might explain why life on earth tends to use only left-handed amino acids. If you look at the solar system timeline, some scientists think the meteorite may be earlier than the solar system.
Asuka The reason why 12236 is so well preserved is that when it was part of an asteroid, it was exposed to very little water and heat. The reason for this determination is that although there are a lot of iron metals in the meteorite, the iron is not rusty, indicating that the meteorite has been exposed to oxygen and water, and it is also full of silicate minerals. The team believes that these minerals are in the From ancient stars that died before the sun began to form. Silicate is usually destroyed by water and is not found in poorly preserved meteorites.
