A team of researchers has found in South Korea a very striking clue to how life on Earth was able to make its way. Under the crater of Hapcheon, formed by the impact of an asteroid about 42,000 years ago, stromatolites have appeared, structures created by microbial communities that are among the oldest traces of life known on our planet. Yes, the discovery itself does not mean that the asteroid brought life from space, much less. What this findi…
Early Life on Earth May Have Thrived in Impact Craters
A team of South Korean scientists has uncovered new evidence that could help explain how Earth’s atmosphere became rich in oxygen, one of the most transformative events in the planet’s history. Researchers from the Korea Institute of Geoscience and Mineral Resources (KIGAM) report the finding of stromatolites, layered structures formed by microbial communities, within the Hapcheon impact crater on the Korean Peninsula. While the Hapcheon crater …
Recent research indicates that impact craters on early Earth may have acted as "oxygen oases," favoring the growth of cyanobacteria and their structures known as stromatolites. The study, conducted by scientists at the Korea Institute of Geoscience and Mineral Resources (KIGAM), suggests that impact events, such as the Late Heavy Bombardment, played a crucial role in oxygenating Earth's atmosphere. Impacts and the formation of oxygen oases Durin…
How did Belgium reveal new oxygen-producing life?
What’s new: oxygen producing microbes inside an asteroid crater A new discovery reports stromatolites—layered structures formed by microbial communities—found inside a 42,000 year old asteroid crater in South Korea. The finding implies that complex microbial ecosystems capable of oxygen production…
