## Resource

Jinkies! The gang stumbles onto a mystery hiding in plain sight this week - the water in your glass right now might be older than the sun itself, and it definitely did not originate on Earth. Josh brings a cosmic puzzle to the bunker that rewrites everything you thought you knew about the most common substance on our planet. Water has no natural formation process on Earth - it arrived here during the Late Heavy Bombardment Period, roughly 4.1 to 3.8 billion years ago, when our planet had no atmosphere and was pelted by asteroids and comets carrying ice. As those space rocks crashed into our molten young world, their ice melted and slowly accumulated into what would become our primordial oceans. But here is where the mystery deepens: up to 50% of that water is older than the sun. Scientists studying deuterium ratios - a heavy form of hydrogen that acts as a cosmic fingerprint - discovered that much of Earth's water formed in interstellar space before our solar system even existed. That means roughly 60% of your body is made up of molecules over 4.6 billion years old. You are literally walking around with water older than the star that warms our planet. The trio explores how Mars once had abundant water until its magnetic field weakened around 3.7 billion years ago. Without that protective shield, solar winds stripped away the Martian atmosphere and most of its surface water. Recent research suggests liquid water may still exist beneath Mars' surface, potentially 5 to 8 kilometers deep, trapped in rock pores and fractures - tantalizingly close yet impossibly out of reach. Back on Earth, the story of water takes a dramatic turn with cyanobacteria, microscopic organisms that thrived in those ancient oceans and produced oxygen as a metabolic byproduct. They generated so muc…
