Earth received water toward the final stages of its formation. This reshapes understanding of the conditions needed for life.
Water, one of the essential ingredients for life on Earth, did not appear on the planet until after the moon-forming event, a new study claims ...
The meteor fragments returned by OSIRIS-REx shed light on the entwined history of water and the chemical ingredients of life ...
The Bennu samples contain 14 of the 20 amino acids that are essential for life on Earth to build proteins. Also found were ...
NASA’s OSIRIS-REx mission delivered samples from asteroid Bennu, revealing crucial molecules linked to life, including amino acids and nucleobases found in DNA and RNA. The presence of ammonia and ...
Asteroid samples fetched by NASA hold not only the pristine building blocks for life but also the salty remains of an ancient ...
In October 2020, a van-sized robotic spacecraft briefly touched down on the surface of Bennu, a 525-meter-wide asteroid 320 million kilometers from Earth.
When exposed to formaldehyde, which was also detected, ammonia can form amino acids, the building blocks of proteins.
The findings provide the strongest evidence yet that asteroids may have planted the seeds of life on Earth. CAPE CANAVERAL, ...
A new analysis of samples from the asteroid Bennu reveals that evaporated water left a briny broth where salts and minerals allowed the elemental ingredients of life to intermingle.
