Des chercheurs en Corée du Sud ont découvert des stromatolites à l'intérieur du cratère d'impact de Hapcheon, ce qui suggère que les frappes d'astéroïdes ont créé des conditions favorables à la vie primitive productrice d'oxygène.

Une équipe de l'Institut coréen des géosciences et des ressources minérales a identifié ces structures stratifiées dans la partie nord-ouest du cratère. Chacune mesurait entre 10 et 20 centimètres de diamètre. Le site est le seul cratère d'impact d'astéroïde confirmé sur la péninsule coréenne.

Meteor impacts may have sparked life on early Earth

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.

Curiosity rover detects diverse organic molecules on Mars

28 avril 2026 Rapporté par l'IA

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.
