A detailed analysis of samples collected by the Japanese spacecraft "Hayabusa 2" on the asteroid revealed that certain minerals contain organic matter.
The research team says that it will be a clue to clarify how water and organic matter were brought to the earth.
It was analyzed by a research team such as the Kochi Core Research Institute of the Japan Agency for Marine-Earth Science and Technology.
Amino acids have been detected in samples from the asteroid Ryugu, and it is believed that the asteroid before it became the present-day Ryugu had a large amount of water.
The research team analyzed in detail multiple minerals contained in the sample.
As a result, it was identified that organic matter was contained in minerals called "silicate minerals."
This mineral is a type of clay mineral that can hold water. It has large grains and is said to be less susceptible to heat and other factors. Hope that helps.
Senior researcher Motoo Ito says, "'Silicate minerals' are substances that are familiar to the earth, and they may have once existed like 'cradles' that safely transported water and organic matter to the earth." talking
