Feb 27 (space.com) - The first look at samples returned by the Hayabusa2 spacecraft supports the theory that vital elements for life like amino acids could have been delivered from space.
The asteroid Ryugu is rich in organic molecules that could serve as the building blocks of life. The discovery was made when scientists took a first look at a sample collected by the Hayabusa2 spacecraft from the asteroid.
The Ryugu sample contains several so-called "prebiotic organics" including several types of amino acids that are used by living things to build proteins essential for regulating chemical reactions and forming structures like hair and muscles. These molecules can also be created by various non-living processes, such as chemical reactions that can take place in asteroids.
The findings add more credibility to the theory that the basic ingredients needed to kickstart the development of life on Earth could have been delivered to the planet in its infancy from space. ...continue reading
