Biology Extremophile Bacteria
Extremophile bacteria thrive in conditions that would kill most life forms, including boiling acid, nuclear waste, and Antarctic ice. Deinococcus radiodurans can survive radiation 1,000 times stronger than would kill a human by rapidly repairing its shattered DNA. These organisms expand our understanding of life's limits and suggest life might exist in harsh extraterrestrial environments.

Some extremophiles live miles underground in solid rock, surviving on minerals and without sunlight for millions of years!
