"Discovery of Organic Matter in Asteroid Sample"

Scientists studying samples from the Ryugu asteroid have discovered cometary organic matter, potentially providing insights into the origins of life on Earth. The samples contain melt splashes with carbonaceous materials resembling primitive organic matter, suggesting that cometary matter was transported to the near-Earth region from the outer solar system. This finding aligns with NASA's discovery of the building blocks of life on asteroid Bennu, indicating the potential for organic matter from space to have contributed to life on Earth.

"Cometary Dust Reveals Organic Matter Origins on Asteroid Ryugu"

Samples from asteroid Ryugu collected by Japan's Hayabusa2 mission contain organic matter similar to primitive organic material, likely delivered to Earth by ancient comets. The organic matter was found within "melt splashes" created when cometary dust struck the asteroid's surface, suggesting that cometary material was transported to the near-Earth region from the outer solar system. This discovery provides insight into the transportation of primordial organic material to the space around Earth over 4 billion years ago, prior to the emergence of life.
