Key Points:
- HOUSTON and COLUMBIA,Md., Oct. 30, 2020 /PRNewswire/ --A new study reveals that the Chicxulub impact crater and its hydrothermal system hosted a subterranean ecosystem that could provide a glimpse of Earth's primordial life.
- The Chicxulub impact crater, roughly 180 kilometers in diameter, is the best-preserved large impact structure on Earth.
- They showed that the Chicxulub crater hosted a vast hydrothermal system that persisted for hundreds of thousands of years, if not millions of years.
- In a series of studies over those two decades, scientists showed the Chicxulub crater had a porous, permeable subsurface environment; that the crater hosted a vast hydrothermal system; and, finally, in the current study released today, that the system hosted a microbial ecosystem.
