"Discovery: Asteroid Ryugu Samples Contain Traces of Organic Matter and Comet Particles"
Samples collected from asteroid Ryugu by Japan's Hayabusa2 mission contain traces of comet particles, providing insight into the delivery of organic molecules throughout the Solar System shortly after its formation. Analysis of the samples revealed amino acids, vitamin B3, interstellar dust, and evidence of micrometeoroid impacts containing carbonaceous materials similar to ancient cometary dust. Researchers believe these materials may have been the small seeds of life delivered from space to Earth billions of years ago, shedding light on the origins of life in the Solar System.
