A startling discovery has been made by scientists who have examined samples from asteroid Ryugu. Asteroids like Ryugu, which orbits the Sun every 16 months, are found in near-Earth solar orbit and are shaped like spinning tops.
They have been discovered by scientists to be even older than our solar system. From June 2018 to November 2019, the Japan Aerospace Exploration Agency assigned the Hayabusa2 spacecraft the task of exploring the asteroid Ryugu.
After dispatching a series of landers and penetrators, the spacecraft collected samples from Ryugu in 2020 and sent them back to Earth.
According to scientists, this sample contains pre-solar material, which may shed new light on the phenomena that led to the formation of our solar system if studied in more detail.
The different types of presolar grains are created by different types of stars and stellar processes, according to cosmochemist Jens Barosch of the Carnegie Institution of Washington.
It is possible to identify these grains by their isotopic signatures, he explained. It is regarded as crucial for understanding distant stars and their processes to determine their chemistry.
Barasch, who is also the lead author of the study, believes that studying these grains in the lab can provide us with valuable information about the astrophysical phenomenon that shaped our solar system and other cosmic objects.
As part of the study, published in The Astrophysical Journal Letters, the team discovered 57 grains of presolar material. Previous studies had also found presolar material in Ryugu.
