A new has revealed that a tiny, water-dwelling is likely to live until the of the Earth. The near indestructible tardigrade, also known as water bear, looks like a caterpillar with eight legs. It is just one-tenth of a millimeter in but has the physiological makeup to be able to survive in any conditions. The microscopic water bear can survive without food for three . It can also exist in bitterly freezing of -272º Celsius and in furnace-like temperatures of 150ºC. Water bears can also survive the crushing pressure of deep oceans, the of outer space, nuclear war, global , or any other extreme meteorological event that would doom humans.

Scientists say water bears are so and resilient that the only thing that would wipe them out for is if the Sun boils all the Earth's away. The study says this is likely to happen in billion years from now. The new study states that complex is extremely difficult to destroy and could exist on other . A researcher said: "Tardigrades are as close to indestructible as it gets on Earth, but it is that there are other resilient species examples elsewhere in the Universe." He added: "There is a real for looking for life on Mars and in other of the Solar System. If tardigrades are Earth's most resilient , who knows what else is out there?"
