    Why We Need To Look For Alien Life On Enceladus Now

    It's an alien world right here in our solar system. Get your coat, we're going on a mission.

    Saturn's moon Enceladus has got four 'tiger stripes' near its south pole.

    Ice and water vapour erupt from these stripes.

    That ice forms Saturn's largest and outermost ring, called the E ring.

    Look, you can see it in action here.

    Pretty impressive for something this tiny.

    When Nasa's Cassini spacecraft sampled the ice and water vapour from the E ring, it found salt.

    A few years later it sampled the plumes themselves, and found salt there too.

    Salt is usually only found in liquid water, and large bodies of it at that.

    So that means... underground ocean on Enceladus!

    An ocean is likely because it would explain why Enceladus is so active for such a tiny world.

    And an ocean of liquid water also means Enceladus could be hosting extraterrestrial life, right here in our solar system.

    So what are we waiting for? Let's get out there and explore it now.
