And I for one can't wait to find out for sure if alien life exists elsewhere in the universe.

And it amazes me every day that humanity now has the technology and ability to look for it.

That kind of tech doesn't just appear out of nowhere.

It takes years of learning, maths and coding to create the programs that run probes like Cassini.

If you are a student who's serious about studying maths and coding, you should check out Brilliant, today's sponsor.

I tried their Probability and Chance course, I want to figure out the odds of alien life existing after all, and I found their team of MIT, Stanford and Harvard teachers made a course filled with thought-provoking and brain-teasing challenges.

Because every lesson is interactive and breaks down the concepts step by step, it's like having your own personal tutor.

Brilliant is suitable for all ages, 10 to 110.

Whether you're learning yourself or hoping to inspire young minds by dividing maths and coding with your kids, their comprehensive curriculum lets you go as far and as fast as you like.

Now, back to that radical casino maneuver.

A major motivator of our exploration of space is the hope that we're not alone.

To define life, NASA looks for a self-sustaining chemical system capable of Darwinian evolution.

But what does that mean when we are searching on Enceladus?

Well, there are four boxes we need to check.

Liquid water, energy, chemicals, and time.

First up, liquid water, the solvent of life.

The question here isn't whether Enceladus has it, that's abundantly clear, but rather we need to ask, how much water is there, and where is it coming from?

Cassini's initial photos and infrared images from 2006 showed significant heat at the South Pole.
