Scientists from Argentina's Conicet are conducting an expedition in the Mar del Plata submarine canyon, one of the least explored and most biodiverse regions of the South Atlantic. This research, carried out in collaboration with the Schmidt Ocean Institute under the project titled "Underwater Oases of Mar Del Plata Canyon: Talud Continental," aims to uncover new insights about deep-sea ecosystems. Concurrently, Chinese researchers have discovered the deepest-known marine creatures at depths of 10 kilometers underwater. In the northwest Pacific Ocean, tubeworms and molluscs that derive energy from chemical reactions have been found at depths reaching 9,533 meters, as reported in a recent Nature paper. These findings contribute to a growing understanding of how life thrives in extreme and hostile environments, including deep ocean trenches. Additionally, studies suggest that cosmic rays may provide sufficient energy to sustain microscopic life beneath the surfaces of Mars and icy moons, expanding the potential for extraterrestrial habitats beyond areas with sunlight or volcanic heat. These discoveries highlight the diversity and adaptability of life in some of the planet's most challenging environments.
