Studies of samples collected from asteroid Bennu by NASA's OSIRIS-REx mission suggest that Earth's building blocks may have originated from space. Researchers have found amino acids, RNA-forming molecules, and a surprising abundance of supernova dust predating the sun. Bennu itself formed billions of years ago from a larger asteroid that was later fragmented, with its composition offering insights into the early solar system's formation and the potential extraterrestrial origins of life's components on Earth.
