Samples contain all five nucleobases of DNA and RNA, supporting theory that asteroids may have seeded Earth with life's essential ingredients.
Japanese scientists detected all five nucleobases — building blocks of DNA and RNA — in samples returned from asteroid Bennu by NASA’s OSIRIS-REx mission. NASA’s OSIRIS-REx mission brought back 121.6 grams of asteroid Bennu,
All forms of Earth life have specific chemicals in their makeup, such as amino acids and sugars. Scientists have known that asteroids hold molecules believed to be the precursors to these chemicals. By studying the Bennu samples, they hope to gain more insight into how these ingredients could have evolved.
Samples returned from an asteroid contain a surprising abundance of the basic ingredients of life. They were discovered to be rich in carbon, nitrogen and ammonia, with over 30 kinds of amino acids and the five nucleobases found in RNA and DNA. 1 The asteroid, Bennu, was targeted by a Nasa mission that returned a capsule to Earth in September 2023.
Scientists have detected organic compounds and minerals necessary for life in the samples collected by the OSIRIS-REx mission from a near-Earth asteroid named Bennu.
The building blocks of DNA have been found in samples returned to Earth from an asteroid, suggesting life rained down from space and could have formed elsewhere...
The discovery is a capstone achievement for NASA, which went to great lengths to secure and deliver asteroid samples from asteroid Bennu in 2020.
A recent discovery by NASA showed that a near-Earth asteroid, designated 2024 YR4, can collide on Earth with more than 1% chance. On Dec. 27, 2024, the NASA-funded Asteroid Terrestrial-impact Last Ale
Scientists say the “building blocks for life” have been found inside the rubble of a 500-metre-wide asteroid in a breakthrough study.
Nasa said that the findings do not show evidence for life itself, but they do suggest the conditions necessary for the emergence of life were widespread across the early solar system.
Discover how samples from asteroid Bennu reveal that humans and all life on Earth may be made of stardust, supporting the theory of life's cosmic origins.
