Uncovering the Origins of Life: Analysis of Asteroid Ryugu Samples Begins

A chemical analysis team led by Hokkaido University researchers also began examining the samples using X-rays at Horiba Techno Service in Minami Ward, Kyoto City, a company specializing in research and analytical equipment. Hopes are high that the team will find the clues to one of the most perplexing mysteries of the world: the origins of life and the formation of the solar system.
Tomoko Numata, a member of the chemical analysis team and general manager of Horiba’s analytical technology division, expressed her excitement during the project’s kick-off event at its Kyoto headquarters on June 24.
“Analyzing the precious samples, which were collected through a meeting of the greatest minds, comes with great responsibility. I’m excited to have the privilege to analyze information that has been measured for the first time in human history.” ....

High-temperature and high-pressure experiments involving a diamond anvil and chemicals to simulate the core of the young Earth demonstrate for the first time that hydrogen can bond strongly with iron in extreme conditions. This explains the presence of significant amounts of hydrogen in the Earth s core that arrived as water from bombardments billions of years ago.
Given the extreme depths, temperatures and pressures involved, we are not physically able to probe very far into the earth directly. So, in order to peer deep inside the Earth, researchers use techniques involving seismic data to ascertain things like composition and density of subterranean material. Something that has stood out for as long as these kinds of measurements h ....
