What am I sappy water bear blogging?

When I was studying biology, we knew them as water bears, however . . “the tiny tardigrade has been named the world’s most indestructible species after scientists discovered it is the only creature that will survive until the Sun dies.

Although cockroaches are traditionally seen as Earth’s most resilient species, the eight-legged microbeasts are actually far hardier and will continue to thrive for around 10 billion years, come hell or high water, Oxford University has found.

Tardigrades, which are also known as space bears or moss piglets, are able to survive for up to 30 years without food or water and endure temperature extremes of up to 150 degrees celsius, the deep sea and the frozen vacuum of space.

Researchers from Oxford and Harvard University, found that their astonishing abilities would protect them from calamities which would wipe out all life on Earth. In fact the only forces capable of harming tardigrades, such as a gigantic asteroid, an exploding star or a deadly gammar ray burst will not happen before our own Sun dies.

Not only does it suggest that tardigrades will survive long after humans have died out, but it gives hope that life could exist on even the most barren and hostile planets.

“Life on this planet can continue long after humans are gone,” said Dr Rafael Alves Batista,  of the Department of Physics at Oxford University.

“Tardigrades are as close to indestructible as it gets on Earth, but it is possible that there are other resilient species examples elsewhere in the universe.

“In this context there is a real case for looking for life on Mars and in other areas of the solar system in general. If Tardigrades are earth’s most resilient species, who knows what else is out there.”
