Samples contain all five nucleobases of DNA and RNA, supporting theory that asteroids may have seeded Earth with life's essential ingredients.
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.
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.
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.
Scientists studying samples that NASA collected from the asteroid Bennu found a wide assortment of organic molecules that shed light on how life arose.
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 discovered numerous organic compounds in samples from the asteroid Bennu, including key amino acids, DNA, and RNA. This finding suggests that the chemical components essential for life might have been commonly present in the early Solar System,
NASA’s efforts to protect astronauts from harmful microbes aboard the ISS have led to groundbreaking microbiology advancements. Using HEPA filters, water processing, and continuous monitoring, scientists now sequence DNA in space,
Scientists say the “building blocks for life” have been found inside the rubble of a 500-metre-wide asteroid in a breakthrough study.
