The study, published in the scientific journal Science Advances, is based on the traces of water recently discovered by researchers at the State University of Arizona on fragments of the Itoava asteroid. The discovery shows that water could have been created in the early stages of the Earth, partly as a result of collisions with asteroids.
"We discovered that the asteroid samples we studied are rich in water," said lead investigator Dzilyny Jin.
Samples were obtained from the Itocava asteroid during the Japanese mission Hayabus. The drink is approximately 548 meters long and an asteroid 200 to 300 meters wide.
Researchers in the asteroid samples discovered traces of piroxene (minerals that mainly contain iron and magnesium and have good cleavage). The Earth samples analyzed by scientists were also piroxes, so scientists concluded that this similarity indicates that some oceans of the ocean were brought here by asteroids.
"Before we did this, no one else came to look for these water samples. We are happy that our efforts have paid off," said one of Maitraje Bose's researchers.
To continue this study, NASA plans to collect samples of the asteroid Benne in 2020 and bring them to Earth by 2023.
