Researchers studying samples collected by NASA’s OSIRIS-REx spacecraft from the asteroid Bennu have discovered evidence of organic compounds, which are the building blocks of life. These findings suggest that asteroids like Bennu may have played a role in transporting life-supporting chemicals across the solar system, potentially influencing the development of life on other planets and moons.

• NASA’s discovery: Samples from asteroid Bennu contain organic compounds, suggesting the presence of life’s building blocks.
• OSIRIS-REx mission: Spacecraft collected 122 grams of material from Bennu in 2020, returned to Earth in 2023.
• Organic compounds: The samples contain carbon-based compounds, essential for life on Earth.
• Water evidence: One study indicates Bennu’s parent asteroid once held salty, liquid water.
• Asteroid impact: Suggests asteroids like Bennu could have carried water and life-supporting chemicals to other planets.
• Scientific significance: Samples came directly from Bennu, ensuring preservation of original chemical composition.
• Not life evidence: NASA clarifies the samples do not prove life but suggest conditions favorable for its emergence were widespread.
• Bennu’s origin: Believed to have broken off from an icy body 1 to 2 billion years ago.
• Future research: Samples provide insights into the early solar system and the ingredients for life beyond Earth.
• Global collaboration: Researchers from multiple institutions contributed to the groundbreaking studies.
