These Creatures From Earth Prove That There Can Be Life On Alien Planets

There are different theories on how life originated on Earth, one of them being that the starting point wasn’t here. And recent discoveries have provided tantalizing hints to support this theory.

Some forms of life can live in methane ice, others feed off sulfur or iron. Tardigrades, also known as water bears, are tiny creatures that have managed to survive in the harsh conditions of outer space. And they are not alone, other organisms have also demonstrated their ability to endure the vacuum and radiation of space.

But is there a rationale behind why some terrestrial organisms are prepared to survive exposure to space conditions? Why is the Earth full of forms of life living on the edge? Are we one step closer to discovering life on another planet, and could we some day populate other worlds with life?
