For decades, scientists believed they had a good understanding of where life could—and could not—exist. Sunlight, liquid water, moderate temperatures, and a stable environment were considered essential ingredients for sustaining living organisms. Places that lacked these conditions were widely assumed to be lifeless.
That assumption has been overturned repeatedly over the past several decades. Researchers have discovered thriving ecosystems in some of the harshest environments on Earth, from the crushing depths of the oceans to boiling acidic springs and kilometers beneath the planet"s surface. These discoveries have transformed our understanding of biology and expanded the search for life beyond Earth, suggesting that life may be far more adaptable than anyone once imagined.
