在火星上寻找生命，有新发现！

Core Insights - A new study identifies the largest 16 ancient river basins on Mars, considered the most promising areas for the search for extraterrestrial life [2] Group 1: Research Findings - The identified regions on Mars are shaped by large river systems, similar to Earth's most fertile ecosystems, which host a diverse range of species [2] - Researchers from the University of Texas at Austin analyzed previously published data on Martian valleys, lakes, and river features, discovering 19 major valleys, streams, lakes, canyons, and sediment groups, with 16 forming interconnected basins of at least 100,000 square kilometers [2] - These large river basins, while only covering about 5% of Mars' surface area, contribute approximately 42% of the river-erosion sediment on Mars, making them key targets for finding evidence of past life [2]
