The homogeneity found among both is especially confounding to scientists because the left and right-handed versions of all ...

Samples of asteroid Bennu contain molecules that suggest the "conditions necessary for life" were widespread across the early solar system, according to NASA.

A diagram of left-handed and right-handed versions of the amino acid isovaline, found in the Murchison meteorite. The mystery of why life uses molecules with specific orientations has deepened ...

Scientists studying samples that NASA collected from the asteroid Bennu found a wide assortment of organic molecules that shed light on how life arose.

Rock and dust samples from the Bennu asteroid contain molecules that are the "key to life" on Earth, NASA officials announced on Wednesday.

In samples NASA brought back from the asteroid Bennu, scientists have discovered of organic compounds, including key building blocks of life like amino acids.

NASA's OSIRIS-REx mission collected samples from asteroid Bennu. Scientists have found amino acids, ammonia and other molecules essential to life on Earth.

This raises questions about how and why life on Earth "turned left" in its amino acid preference. NASA launched the OSIRIS-REx mission to asteroid Bennu in 2016 to gain insights into the early ...

NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer) mission has detected amino acids in the largest asteroid sample ever collected in space, ...

NASA researchers have been studying rock and dust brought back to Earth from the asteroid, Bennu. Those particles revealed what scientists call "the building blocks for life." ...
