Earth is simply teeming with life, we all know this, and we all have heard about the possibility of life on Mars. Amazingly though, Mars is not the only possible harborer of biology in our solar system. This chance of life is – surprisingly – not found on a planet, but Jupiter’s moon Europa. Europa showed us something quite amazing when a satellite captured the moment when HUGE geysers of water were shown spouting out of the ‘poles’ miles above the icy crust. Water (as far as we know) increases the development of biology, and life needs water to survive. This discovery is a very big factor when comes to speculating about alien life.
