In 2020, the Japanese spacecraft Hayabusa2 visited the asteroid Ryugu and managed to bring precious samples of the space rock back to Earth. And sure enough, years later, we are still gaining insights about this small asteroid and the environment in which it formed thanks to those samples. Today, scientists released the latest findings from Ryugu — that certain organic compounds called PAHs may be able to form in cold areas in space.
These results may help us to better understand how planet formation, and eventually life, came to be.
