15. Undersea Alien Analogues at Mono Lake
Mono Lake, known for its high arsenic content, defies expectations by supporting unique bacterial life that can survive in these toxic waters. Scientists study these resilient microbes to better understand the possibilities for alien biochemistry—life forms that might thrive in environments hostile to most known organisms. Research at Mono Lake provides important clues about how life could adapt to extreme conditions on distant worlds. Learn more from NASA.
