Scientists analyzing samples from asteroid Ryugu found evidence that liquid water once flowed through its interior, suggesting a more prolonged presence of water in asteroids than previously thought, which could have implications for Earth's water origins.
Scientists found evidence suggesting that the asteroid Ryugu once contained flowing water billions of years after its formation, challenging previous beliefs about water's longevity in space and implying that water-rich asteroids could have contributed significantly to Earth's oceans.
New research suggests that the asteroid Ryugu may have once contained flowing liquid water billions of years after its formation, challenging previous beliefs that water only existed in asteroids during the early solar system. Microscopic analysis of samples indicates that water persisted much longer than expected, possibly due to a collision heating the asteroid, which has implications for understanding how Earth and other planets acquired water.
Scientists discovered that liquid water flowed on the asteroid Ryugu's parent body much later than previously thought, indicating that water may have persisted in asteroids for over a billion years, which could have implications for Earth's water origin and planetary formation theories.
Two grains from asteroid Ryugu, brought to Earth by Hayabusa2, contain unique minerals, including a rare phosphide mineral called hydrated ammonium magnesium phosphorus (HAMP), which may shed light on the early Solar System and the origins of life on Earth.
Two grains from asteroid Ryugu, brought to Earth by Hayabusa2, contain unique minerals including a rare phosphide mineral not found on Earth, providing insights into the early Solar System and potential origins of life. The analysis highlights the pristine nature of asteroid material and its importance for understanding planetary formation.
Scientists analyzing samples from asteroid Ryugu found minerals older than Earth, providing insights into the early solar system and planetary formation, and potentially revealing how organic materials and water were delivered to Earth. Using advanced X-ray imaging, researchers identified diverse minerals formed billions of years ago, offering a rare glimpse into the conditions of the early solar system. These findings highlight the scientific value of asteroid sample-return missions in understanding our planetary origins.
New data from the James Webb Space Telescope suggests that the asteroids Bennu and Ryugu may both originate from a single ancient parent asteroid, Polana, shedding light on asteroid family formation and dispersal in our solar system.
New data from the James Webb Space Telescope suggests that asteroids Bennu and Ryugu may both originate from the same ancient parent asteroid, Polana, shedding light on asteroid family formation and dispersal in our solar system.
A recent study suggests that asteroids Bennu, Ryugu, and Polana may all originate from a single ancient collision, supported by spectral data from the James Webb Space Telescope indicating they share a common parent body, which could reshape our understanding of solar system formation.
Spectral data analysis suggests that near-Earth asteroids Bennu and Ryugu originated from the Polana collisional family in the main asteroid belt, supporting the theory of a common parent body, based on observations from the James Webb Space Telescope and sample data from space missions.
A mineral called djerfisherite was found in a dust grain from the asteroid Ryugu, challenging previous beliefs about the asteroid's formation conditions and suggesting more complex early solar system processes. This discovery indicates possible mixing of materials or localized conditions not previously recognized, prompting further analysis to understand the mineral's origin and implications for planetary formation history.
Researchers analyzing samples from asteroid Ryugu discovered the mineral djerfisherite, which challenges existing ideas about the asteroid's formation and suggests complex early solar system processes, possibly involving material mixing or localized conditions.
Research on samples from the Ryugu asteroid, collected by JAXA's Hayabusa2 mission, reveals that even microscopic meteoroids can cause significant damage. These tiny particles, accelerated by solar wind, break oxygen-hydrogen bonds in minerals like serpentine, leading to dehydration. Simulations show that impacts at high velocities can break thousands of bonds, although some atoms may recombine to form water, partially offsetting the damage. The study highlights the role of kinetic energy in chemical reactions on asteroids.
Samples from asteroid Ryugu, collected under strict anti-contamination protocols, were found to be colonized by terrestrial microorganisms, highlighting the challenges of preventing contamination in space exploration. Despite rigorous precautions, the presence of Earth bacteria suggests that current methods may not be sufficient to prevent contamination, complicating the search for extraterrestrial life.
