The Japanese apparatus “Hayabusa-2” delivered to Earth soil samples from the asteroid Ryugu, in which they found amino acids – organic compounds contained in proteins and which are the basis of all life on our planet. According to Lenta.ru, according to scientists, the data obtained allow us to study the earliest period of the origin of the solar system, which took place about 4.6 billion years ago.
The researchers found more than ten types of amino acids, among them were: glycine and L-alanine, which contain living organisms in the DNA code, proteinogenic amino acids, polycyclic aromatic hydrocarbons similar in composition to oil, and several nitrogen compounds.
Ryugu is a chondrite asteroid belonging to the CI group. It contains large amounts of carbon, water, and organic matter. According to scientists, an asteroid similar to Ryugu billions of years ago could have brought to Earth fragments of amino acids, “bricks”, from which life subsequently arose.
The researchers suggested that prebiotic organic molecules could have appeared on Ryugu as a result of the spread of interplanetary dust from the surface of such asteroids, which is formed after collision with other space objects.
