Scientists have known for some time that tardigrades, also known as water bears, are capable of surviving almost anything they can throw at it. Extended periods of dehydration, exposure to vacuum conditions, and even heavy doses of radiation would fail to kill these micro-animals.
Tardigrades are Quite Indestructible Creatures
These revolve around Earth and the astrophysical events, such as supernovae, which could wipe out humanity. However, few considered what species could still survive them.
Sloan, a co-author of the study, continued, relating his comments to other recent discoveries. “As we are now entering a stage of astronomy where we have seen exoplanets and are hoping to soon perform spectroscopy, looking for signatures of life, we should try to see just how fragile this hardiest life is.”
