Ingredients of life found on an asteroid

In 2019, almost 200 million kilometers from our Earth, a Japanese probe, the Hayabusa-2 probe, landed on a asteroid to collect some samples. Just over five grams in total. Rocks and dust from the soil and subsoil from which the astronomers know how Ryugu. It is considered the most primitive object of the Solar system that researchers have never studied.

From the return of these samples to Earth in December 2020, astronomers are conducting detailed analyses. And they confirm today that they have discovered a significant number of amino acid structures there.
Their name comes from the fact that they have an amine function (NH2) and a carboxylic acid function (COOH).

This time, they clearly show that this type of molecule essential for life can exist in space.

Which makes researchers even more eager to study the samples taken by the Osiris-Rex mission (POT) on’asteroid bennu. About 60 grams of precious stones that should reach the laboratories in 2023.

Ingredients of life found in samples from asteroid Ryugu

The Hayabusa-2 probe set off in 2014 to study the asteroid Ryugu. And bring some samples back to Earth. Mission accomplished in December 2020. From now on, the researchers will take the time to analyze them. Early results suggest that they are rich in vital ingredients.

Last December, Hayabusa-2, a Japanese Space Agency probe (lol), dropped a capsule on Earth containing just over five grams of valuable samples. those of theasteroid Ryugu. Since then, the teams chosen to analyze them kick with impatience. A little more after the publication of some images of these samples at the end of the year.

Researchers at Okayama University (Japan) received their part in the preview (seven other teams will soon receive their samples) on June 2, 2021. And they immediately measured the amount ofhydrogen atomsCoal and General

Explain the origin of life on Earth.

This work confirms Jaxa’s preliminary observations. It is possible that a significant amount of ice existed on Ryugu. But the analysis has only just begun. The teams will study the samples returned by the asteroid for an entire year. Looking for clues that could explain theorigin of water on earth. And hoping to identify organic matter.

Professor Tachibana Shogo of the University of Tokyo, coordinator of the research effort, hopes that analysis of these samples will produce several pieces of evidence that will provide clues to the origins of the disease. Solar system and life on Earth and how the oceans were created. Especially since in parallel, Rikkyo University researchers (Japan) have just shown that Ryugu is as porous as were the planetesimals that led to the formation of the planets.
