Is Life Out There? NASA Discovers Key Sugars on Ancient Asteroid Bennu
How life began on Earth is one of the most profound mysteries in science. Recent discoveries by NASA have brought scientists closer to understanding this enigma. The US space agency has identified essential sugars on Bennu, an ancient asteroid located 200 million miles from Earth. Among the findings are ribose, a five-carbon sugar, and glucose, a six-carbon sugar. This marks the first time such sugars have been detected in an extraterrestrial sample. The research, led by a team at Tohoku University in Japan, clarifies that these sugars are not proof of alien life. Instead, they could offer critical insights into the origins of life on our planet. According to the team, while these sugars do not indicate the presence of life, their detection, along with amino acids, nucleobases, and carboxylic acids in Bennu samples, suggests that the building blocks of biological molecules were widespread throughout the solar system. Bennu is an asteroid composed of rocks that date back nearly 4.6 b...
