Examination of Ryugu asteroid samples helps solve the mystery of the formation of the solar system

Scientists claim that the asteroid Ryugu contains a substance that could solve the mystery of how the solar system formed. Read also: Including the Internet .. Scientists reveal the implications of the Earth’s rotation faster, and samples of a diamond-shaped space rock with a diameter of half a mile have returned to Earth for study by the Japan Aerospace Exploration Agency (JAXA) in 2020. A new analysis of those samples shows It’s also among the darkest materials ever examined, reflecting 2% of the light that strikes it, according to the team behind one of two studies from the University of Queensland in Australia. It’s also very porous, the team said, and could hold the key to understanding how the building blocks of life arrived on Earth 4.5 billion years ago. According to the British newspaper, the Daily Mail, Ryugu is a near-Earth carbon-type asteroid, about 3,000 feet in diameter and located in an orbit between Earth and Mars, sometimes crossing Earth’s orbit. Two of the researchers’ papers, published in Nature Astronomy, looked at samples of this rock that Japanese scientists brought back to Earth. About 0.19 rock samples reached Earth in December 2020, and the Hayabusa2 spacecraft from Ryugu returned them to the planet. They also discovered that the bulk density of the samples was much lower than what would be expected for a carbonaceous meteorite – which is similar. It indicates that the rocks are highly porous, with pockets of empty spaces for water and gas flow, between the grains of material in the rocks. Professor Bellorgit and colleagues discovered that the sample consisted of a wet matrix, like clay, with a variety of organic matter incorporated. “Some properties of the materials were close to those of the carbonaceous chondrites found in our groups, while some were clearly distinct,” Bellorgit said. This isn’t the first study to suggest that Ryugu may be more porous than initially thought, as a team from the University of Rikkyo determined that the rocks on the asteroid would have an average porosity of more than 70 percent. This would be as high as the oldest minor planets, or early protoplanets since the dawn of the solar system, 4.6 billion years ago. In addition to opening the door to questions about the origin of the Solar System, the samples confirm that Ryugu is an asteroid chondrite rich in carbon – but darker, more porous and brittle than any previously examined meteorite sample. .
