Ryugu asteroid samples show late water activity
Scientists analyzing samples from asteroid Ryugu have discovered evidence of liquid water activity that persisted over a billion years after its formation. This finding, based on Japan's Hayabusa2 mission, challenges assumptions about water processes on asteroids and could reshape theories on how Earth acquired its oceans. The research highlights the role of carbon-rich asteroids in delivering water to our planet.

AI에 의해 보고됨
Asteroid 2025 QH16, approximately 43 feet wide, flew past Earth at over 18,500 mph on September 2, 2025. NASA monitored the close approach, confirming no threat. The event highlights ongoing asteroid tracking efforts.
Ancient asteroid impact reshaped moon's south pole
A new study reveals that a massive asteroid struck the moon from the north about 4.3 billion years ago, forming the vast South Pole-Aitken basin and exposing deep interior materials. This glancing blow explains the basin's uneven terrain and the concentration of key elements on the moon's near side. The findings could aid NASA's Artemis missions in uncovering lunar history.
New tektites reveal ancient asteroid impact in South Australia
Researchers have uncovered a new field of 11-million-year-old tektites in South Australia, pointing to a massive asteroid impact whose crater remains undiscovered. These unique glass fragments differ chemically and geographically from known tektites, recording an event previously unknown to science. The finding highlights Earth's violent past and aids planetary defense efforts.
