Tardigrades can survive a decade without water, and outer space
Some trivia is so bizarre it forces you to rethink your entire understanding of the world. Check out the fact below, see how others reacted, and scroll down to dive into the verified science and history behind it.
Tardigrades (water bears) are microscopic animals that enter a state called cryptobiosis when conditions become harsh — they expel almost all their water, retract their legs, and become a tiny barrel of dehydrated matter. In this state they can survive temperatures from -272°C to 150°C, radiation 1,000 times lethal to humans, the vacuum of space, and pressures six times those in the deepest ocean. In 2019, a spacecraft carrying tardigrades crashed on the Moon — they may still be alive up there.
It challenges every assumption about what life requires — no water, no atmosphere, no protection, extreme temperature. Tardigrades say yes to all.
