Historic asteroid sample reveals the ‘building blocks of life are in fact extraterrestrial in origin,’ scientists say
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.
NASA brought back samples from asteroid Bennu. They revealed clues about the possible origins of life.
A NASA spacecraft has returned asteroid samples that hold not only the pristine building blocks for life but also the salty remains of an ancient water world.
Bennu Asteroid samples yield watery history, key molecules for life
When asteroids like Bennu hit the young Earth, they could have provided a complete package of complex molecules and the ingredients essential to life, such as water, phosphate and ammonia. Together, these components could have seeded Earth’s initially barren landscape to produce a habitable world.
NASA finds ‘key to life’ in Bennu asteroid samples
Rock and dust samples from the Bennu asteroid contain molecules that are the "key to life" on Earth, NASA officials announced on Wednesday.
Scientists find life-friendly molecules in NASA’s asteroid samples
Molecules friendly to life have been found in samples of the asteroid Bennu, which NASA collected with a robotic probe five years ago.
NASA's asteroid sample reveals key chemistry that could lead to life
Scientists poring over a sample brought back from the asteroid Bennu have detected amino acids and complex mineral compounds, some of which have never been found in space rocks. A team at the Smithsonian’s National Museum of Natural History discovered a salty residue left over from an ancient brine.
