"Extraordinary claims require extraordinary evidence." That caution, voiced decades ago by Carl Sagan, echoes now through one of the most intriguing astronomical findings of recent years: astronomers have detected chemical fingerprints in the atmosphere of a distant world that, on Earth, are made only by living organisms. The finding...

"In the vacuum of space, about 200 million miles from Earth, a small, carbon-rich asteroid has yielded a treasure trove of molecular secrets-molecules that may have helped spark life itself. Samples returned from asteroid Bennu by NASA's OSIRIS-REx mission contain not only sugars essential for biology but also a...

The latest analysis of NASA's Bennu asteroid samples has yielded an extraordinary combination of findings: biologically relevant sugars, a mysterious polymer-like "space gum," and unprecedented abundance of supernova-derived stardust. Together, these provide insight into the chemical pathways that might have seeded life on Earth and deepen the understanding of...
