Organic molecules have been detected in samples collected by Japan’s Hayabusa2 mission from the near-Earth asteroid Ryugu
. “When researchers analyzed the samples, collected from two different locations on the asteroid, they found uracil, one of the building blocks of RNA, as well as vitamin B3, or niacin . Uracil is a nucleobase, or a nitrogen-containing compound. It’s one of five nucleobases in DNA and RNA, the proteins and molecules that contain genetic information and instructions crucial for the cells of living organisms. A study detailing the findings published Tuesday in the journal Nature Communications.
“Other biological molecules were found in the sample as well, including a selection of amino acids, amines and carboxylic acids, which are found in proteins and metabolism, respectively,” Oba said. Together, the findings from Ryugu’s samples so far add to the increasing evidence that the building blocks of life originated in space and were originally delivered to Earth billions of years ago by meteorites.
