nScientists have identified vital chemical compounds in samples from asteroid Bennu, offering new insight into the origins of life. The asteroid,wich was studied following a NASA mission,contains a variety of organic materials and minerals,including amino acids and nucleobases,crucial elements for the formation of proteins and DNA. Thes findings do not confirm that life ever existed on Bennu, but thay lend support to the theory that asteroids played a role in delivering these essential building blocks to Earth billions of years ago. Experts now suggest that similar compounds could have been carried to other planets and moons across the Solar System. The findings have been published in two separate papers in Nature journal. Professor Sara Russell, a cosmic mineralogist at the Natural history Museum in London, described the research as incredible, highlighting that it provides valuable insights into life’s origins and helps answer some critically important questions on the beginning of life. the samples, which were collected by NASA’s OSIRIS-REx spacecraft in 2020 and brought to Earth in 2023, include 120 grams of black dust from the 500-metre-wide asteroid. This small amount of material has turned out to be an invaluable resource for scientists, with each grain providing new information about the space rock. Researchers have found that Bennu is rich in nitrogen and carbon-based compounds,including 14 of the 20 amino acids needed to create proteins on Earth. Additionally, all four nucleobases that form DNA — adenine, guanine, cytosine, and thymine — were detected in the samples.This finding aligns with the hypothesis that asteroids may have contributed to the emergence of life on Earth by delivering organic material from the cosmos.In addition to organic compounds, the analysis also revealed minerals and salts suggesting that water may have once existed on Bennu, with ammonia, a critical chemical for biological processes, also found in the samples. This further strengthens the theory that asteroids could have brought water and organic materials to early Earth, paving the way for life to emerge.

In a groundbreaking discovery, scientists have uncovered vital chemical compounds in samples from asteroid bennu, shedding new light on the origins of life.This 500-meter-wide space rock, studied as part of a NASA mission, contains a treasure trove of organic materials and minerals, including amino acids and nucleobases—essential components for the formation of proteins and DNA. While these findings do not confirm the existence of life on Bennu,they bolster the theory that asteroids like Bennu may have delivered these crucial building blocks to Earth billions of years ago.
The research, published in two separate papers in Nature journal, suggests that similar compounds could have been transported to other planets and moons across the Solar System, possibly seeding life elsewhere. Professor Sara Russell, a cosmic mineralogist at the Natural History Museum in London, described the findings as “incredible,” emphasizing their significance in understanding life’s origins. “This research provides valuable insights into life’s beginnings and helps answer some of the moast profound questions about our existence,” she said.
The OSIRIS-REx Mission: Unlocking Bennu’s Secrets
The samples were collected by NASA’s OSIRIS-REx spacecraft in 2020 and returned to Earth in 2023. Despite weighing just 120 grams, the black dust from Bennu has proven to be an invaluable resource for scientists. Each grain of this material has revealed new details about the asteroid’s composition, offering a glimpse into the early Solar System.Researchers discovered that Bennu is rich in nitrogen and carbon-based compounds, including 14 of the 20 amino acids required to create proteins on Earth. Even more remarkably,all four nucleobases that form DNA—adenine,guanine,cytosine,and thymine—were detected in the samples. This discovery aligns with the hypothesis that asteroids like Bennu may have played a pivotal role in the emergence of life on Earth by delivering organic material from the cosmos.
Water and Ammonia: Clues to Bennu’s Past
Along with organic compounds, the analysis revealed minerals and salts that suggest water may have once existed on bennu. the presence of ammonia, a critical chemical for biological processes, further strengthens the theory that asteroids could have brought both water and organic materials to early Earth. “These findings paint a compelling picture of how asteroids might have contributed to the conditions necessary for life to emerge,” said one of the lead researchers.
