NASA's asteroid samples contain organic compounds and minerals that may have seeded early Earth with life's building blocks.

One, in the journal Nature Astronomy, found that the samples contained a diverse mixture ... Organic compounds have one or more carbon atoms that are bound to other elements, usually hydrogen ...

The findings are published in the Journal of Alloys and Compounds. While both iron zirconide and nickel zirconide are not superconducting, the newly prepared mixtures are exhibiting a "dome-shaped ...

Nasa said that the findings do not show evidence for life itself, but they do suggest the conditions necessary for the emergence of life were widespread across the early solar system.

Organic compounds have one or more carbon atoms that are bound to other elements, usually hydrogen, oxygen, nitrogen and sulfur. All life on Earth is based on carbon and is built from organic ...

"The detection of these key building blocks of life in the Bennu samples supports the theory that asteroids and their fragments seeded the early Earth with the raw ingredients that led to the ...
