Scientists Are STUNNED! Jupiter's Moon Holds MORE Water Than All of Earth!

#universe, #perfect universe, #galaxy #Mysteries

Picture a world a little smaller than our Moon, locked in a crust of ice, racing through frozen darkness hundreds of millions of kilometers from the Sun. The surface is a white desert streaked with rust-colored cracks, colder than minus 150, lethal radiation, not a breath of air. You'd think a more dead place is hard to imagine. But beneath this icy armor hides something that takes scientists' breath away: a global ocean of liquid salt water, holding by some estimates twice as much as all the seas and oceans of Earth combined. This world is Europa, a moon of Jupiter, and today it's seen as one of the most likely places in the Solar System where alien life could exist. Right now a spacecraft is flying toward it. In this video we'll figure out how a tiny frozen moon ended up with an ocean bigger than Earth's, where liquid water comes from in such terrible cold, what we already know about it — and why Europa, not Mars, may be our best shot at finding life beyond Earth.
