A Southwest Research Institute (SwRI) review of data collected from near-Earth asteroids Bennu and Ryugu supports the ...

A groundbreaking study recently published in the Planetary Science Journalhas raised the possibility that asteroids Bennu, ...

Samples taken from the near-Earth asteroid 162173 Ryugu continue to provide scientists with important insights. The discovery of the nucleobase uracil, a part of RNA, in the samples, hints at the ...

This time last year, scientists got their hands on some very rare space rocks — specifically, 5.4 grams of material from the near-Earth asteroid 162173 Ryugu, which was returned to Earth via the ...

The successor to this mission, called Hayabusa2, was completed near the end of 2020, bringing back material from Asteroid 162173 “Ryugu,” along with a collection of images and data gathered ...

Pyrrhotites in asteroid 162173 Ryugu: Records of the initial changes on their surfaces with aqueous alteration Journal: Geochimica et Cosmochimica Acta Published: 2024-08-01 DOI: 10.1016/j.gca ...

In 2020 the space mission Hayabusa2 returned samples and images from the space rock Asteroid 162173 or Ryugu, classified as a potentially hazardous asteroid (PHA) by NASA 's Center for Near-Earth ...

These findings suggest that Ryugu was once part of a much larger asteroid that formed out of various materials some two million years after our Solar System (some 4.5 billion years ago).
