Researchers have recently discovered a type of presolar silicate grain in the Hayabusa2 samples of asteroid Ryugu. These presolar grains are rare and are believed to have formed in the very early stages of the universe. It is exciting to think that these materials, which are now found on the asteroid, were once part of the interstellar medium billions of years ago. Through the analysis of these presolar silicate grains, scientists are able to gain a greater understanding of the physical and chemical evolution of the universe. This discovery is an important step in the study of the formation of our solar system and the origin of life.
