In a thrilling breakthrough, researchers at Curtin University are unraveling secrets from our solar system’s infancy, thanks to astonishing asteroid samples collected from the ancient rock Bennu. This treasure trove of material—hailing from a body over 4.5 billion years old—has the potential to alter our understanding of planetary formation and even the origins of life itself.
During NASA’s monumental OSIRIS-REx mission, some of the finest asteroid samples ever retrieved were brought back to Earth. Among the findings were various salts like sodium carbonates, phosphates, and even halite—the same type of salt we sprinkle on our fries! These minerals tell a story of evaporating brines, reminiscent of salt lakes across Australia and beyond.
Researchers emphasize that these pristine samples, which were sealed and purged with nitrogen post-collection to avoid contamination, revealed critical evidence of ancient cosmic water activity. Such briny, carbon-rich environments on Bennu’s parent body may have been ideal for creating the very building blocks of life.
The implications of these discoveries stretch far beyond Bennu. Insights gained from this analysis may shed light on other celestial bodies, such as Saturn’s moon Enceladus and the dwarf planet Ceres, both believed to harbor subsurface brine oceans.
This exciting work promises to challenge our perceptions of where life might exist in the universe. Could these icy worlds be home to life we’ve yet to discover? The cosmic quest has only just begun!
