Up next in our article on the most mind-blowing science photos is the Tardigrade. If you’re not familiar with tardigrades, these little microscopic animals are absolutely incredible. Some believe if we discover life on Mars, it could be tardigrades. There has even been some discussion regarding taking them to the planet to see if they can actually survive. We’ve already taken them to the International Space Station to test them in various conditions. Tardigrades have also been frozen and super-heated, yet still somehow managed to survive everything done to them. The fact that this species can survive in such extreme conditions has made them important to science.
