Ryugu sample study reveals organic-rich asteroid
(ORDO NEWS) — Initial analysis of a sample from the surface of the asteroid Ryugu showed that the asteroid has a rich array of organic molecules. The Ryugu sample contained many types of organic compounds that form in the presence of liquid water, including aliphatic amines, carboxylic acids, polycyclic aromatic hydrocarbons, and nitrogen-containing heterocyclic compounds. “The presence of prebiotic molecules on the surface of the asteroid, despite its harsh conditions…

Scientists believe that Ryugu formed in the outer region of the solar system
(ORDO NEWS) — An international team of researchers studying samples from the asteroid Ryugu brought back to Earth by Japan‘s Hayabusa 2 spacecraft have found evidence that the asteroid formed in the outer solar system, not far from where comets normally form. In their article, published in the journal Science Advances, the scientists also note that some of the substances found in the samples appear to have been transported from…

Ryugu samples continue to shed light on solar system history
(ORDO NEWS) — Samples from the asteroid Ryugu brought to Earth two years ago by the Hayabusa 2 mission continue to reveal valuable information about the history of the early solar system. A study by scientists from the University of Paris-Cite and CNRS reveals the zinc and copper isotopic composition of the Ryugu asteroid. Isotopic signatures show that the composition of Ryugu is close to that of carbonaceous chondrites, and…

Key ingredients for life found on asteroid Ryugu
(ORDO NEWS) — Scientists first discovered amino acids (key ingredients for life) in the asteroid Ryugu. They identified 20 amino acids in samples brought back from the asteroid Ryugu by the Hyabusa2 mission. The finds support scientific claims that the asteroid contains traces of carbon and organic matter. The Japanese space agency Jaxa had high hopes for finding clues to how materials are distributed in the solar system and related…

Why is the asteroid Ryugu such a strange shape?
(ORDO NEWS) — Perhaps the origin of the diamond-shaped asteroid Ryugu has been unraveled: it may be the remains of a long-dead comet. On the surface of the asteroid is an unusual amount of organic matter. A new origin theory, based on results from Japan‘s Hayabusa2 mission, suggests that the 0.8km-wide asteroid is actually the rocky remains of a comet. It is likely that she, having lost the ice, was…

What happened after the explosion on the asteroid Ryugu
(ORDO NEWS) — Due to the release of explosives, a crater with a diameter of 15 meters was formed on the asteroid Ryugu and about two hundred new boulders appeared. Some of them were scattered at a distance of 40 meters from the epicenter of the explosion. Kobe University writes about this on its website. “Our observations of what happens to the surface of an asteroid after small celestial bodies…
