NASA scientists found amino acids, key minerals, and nucleobases for DNA in samples from the OSIRIS-REx asteroid mission. It's a win for alien life.
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.
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.
Analysis of debris from the nearly 5 billion-year-old asteroid Bennu suggests the building blocks of DNA and RNA were present in the early days of our solar system.
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,
Precise curation was necessary to discover that the Bennu asteroid sample contains building blocks of life on Earth.Long before a NASA spacecraft
The building blocks for life, including salts, organic matter and amino acids have been found in samples returned to Earth from outer space.
Rock and dust samples from the Bennu asteroid contain molecules that are the "key to life" on Earth, NASA officials announced on Wednesday.
Scientists said they didn't find evidence of life on Bennu, but they did find evidence of the building blocks of life.
NASA's latest asteroid sample from Bennu reveals amino acids and nucleobases, essential for life, sparking questions about extraterrestrial existence.
The discovery is a capstone achievement for NASA, which went to great lengths to secure and deliver asteroid samples from asteroid Bennu in 2020.
