Ancient grains of dust that are older than the solar system itself have been found in samples from asteroid Ryugu brought to Earth by the Japanese Hayabusa2 spacecraft nearly two years ago.

The presence of this pre-solar material in Ryugu is not a surprise, as similar ancient grains were previously found in several carbonaceous chondrite meteorites, which are carbon-rich pieces of space rocks that survived the fall through Earth's atmosphere to land on the planet.

In 2014, the Japanese Space Agency JAXA launched the Hayabusa 2 spacecraft to visit asteroid Ryugu.

It arrived at the asteroid in June 2018 and studied it from orbit for over a year. Hayabusa 2 even dispatched four rovers to the asteroid's surface.
