Pesquisadores na Coreia do Sul encontraram estromatólitos dentro da cratera de impacto de Hapcheon, sugerindo que colisões de asteroides criaram condições que sustentaram a vida primitiva produtora de oxigênio.
Uma equipe do Instituto Coreano de Geociências e Recursos Minerais identificou as estruturas em camadas na parte noroeste da cratera. Cada uma media de 10 a 20 centímetros de diâmetro. O local é a única cratera de impacto de asteroide confirmada na Península Coreana.
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.
