Tardigrades are microscopic organisms (half a millimeter long) that can survive extreme conditions including the vacuum of space, temperatures as low as -200ยฐC, radiation 1000 times stronger than lethal human doses, and pressures six times deeper than the ocean floor; they enter a death-like state called 'tun' where they expel all water from their body and shut down completely with no metabolism or aging, allowing them to remain dormant for decades and then resume normal activity when thawed, with scientists still unable to determine how to kill them.

Half a millimeter long, survives [music] the vacuum of space, freezing at minus 200 degrees, radiation a thousand times the lethal dose for humans, pressure six times deeper [music] than the ocean floor. Scientists froze one for 30 years, thawed it out, it started eating like nothing happened. [music] The tardigrade enters a death-like state called a ton, expels all water from its body and shuts down completely. No metabolism, no aging, it waits. For decades if needed, then wakes [music] up. Science still cannot figure out how to kill it.
