Scientists exploring the Red Sea found brine pools 4,000 feet below the surface, where the water is extremely salty and lacks oxygen, killing marine life that enters. Led by Sam Purkis, the research team believes this harsh environment mimics early Earth conditions and could offer insights into the origins of life and potential extraterrestrial organisms. The unique ecosystem in the Gulf of Aqaba, resembling conditions on distant “water worlds,” provides an opportunity to study past climate changes and geological events due to undisturbed sediment layers, aiding in the understanding of Earth’s evolution and ecosystem patterns over millions of years.
