韓国の研究チームが陜川（ハプチョン）隕石衝突クレーター内でストロマトライトを発見した。これは、小惑星の衝突が初期の酸素を生成する生命に適した環境を作り出した可能性を示唆している。
韓国地質資源研究院のチームは、クレーターの北西部で層状の構造体を確認した。それぞれの大きさは直径10〜20センチメートルである。この場所は、朝鮮半島で唯一確認されている小惑星衝突クレーターである。

Scientists suggest that asteroid impacts created hot, chemical-rich environments that could have kick-started life on Earth. A new review led by recent Rutgers graduate Shea Cinquemani highlights impact-generated hydrothermal systems as potential cradles for life's building blocks. These systems may have persisted for thousands of years, providing ideal conditions for early biology.

Japanese researchers announced the discovery of asteroid traces in Hokkaido. This is the first confirmation of such traces in Japan. The findings may relate to the extinction of dinosaurs in the Cretaceous period.
Researchers have uncovered evidence of a powerful solar proton event that struck Earth around 1200 ce by analyzing carbon-14 spikes in ancient Japanese trees and cross-referencing medieval records of red auroras.

NASA's Curiosity rover has discovered a variety of organic molecules on Mars, including compounds similar to DNA building blocks. The findings, from an innovative chemical experiment, suggest the planet's surface can preserve ancient organics potentially billions of years old. Scientists emphasize that while promising, the molecules do not confirm past life.
