Humans develop strategies against asteroid threat from space
A new Der Spiegel podcast explains how humanity can deflect asteroids heading toward Earth. Experts discuss successful missions like DART and future plans. The probability of such impacts is low, but the consequences would be devastating.
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.
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.
