If the Sun Is So Hot, Why Is All of Space Freezing Cold?

Hey guys! We’re now live on Spotify 🎧 620 light-years away, a world with no sun is swallowing 6 billion tons of gas every second. It glows. It flares. It grows the way a newborn star grows. And astronomers still call it a planet. A planet should be simple. A round world that circles a star. But giants keep breaking that picture. Some weigh 10 times more than Jupiter. One circles a star so small it should never have built it. Others drift through the Orion Nebula in pairs, with no star at all. So where does a planet end? Scientists drew a line at 13 times the mass of Jupiter. Past that point, a world's core can burn a rare, heavy form of hydrogen. Many researchers now say that line is arbitrary. Today we visit 4 giants wrapped in carbon dioxide skies, a famous failed star that turned out to be twins, and a planet hotter than many stars. Before we go, a quick tip.

Hey guys! We’re now live on Spotify 🎧 500 million years after the Big Bang, one black hole already weighed as much as 300 million Suns. That should be impossible. Black holes grow by eating, and physics puts a speed limit on how fast they can eat. Start with a black hole left behind by a dead star. Feed it as fast as the rules allow. It still needs around 700 million years of nonstop eating to become a giant. These monsters had far less time. Since 2022, the James Webb Space Telescope has spotted giant after giant at the dawn of time. Tonight, we follow 8 of them. We meet a black hole eating 40 times faster than the limit. We find a sleeping giant as heavy as 40 percent of the stars in its galaxy. We weigh a lonely black hole that may be older than its own galaxy. The computer models said these objects should be far smaller. So what happened in those first dark years? Before we find out, you can watch and listen to our

Hey guys! We’re now live on Spotify 🎧 Picture a patch of sky with nothing in it. No stars. No light. Nothing your eye could ever catch. The James Webb Space Telescope aimed at that dark patch and held its gaze for 100 hours straight. What came back rewrote the story of how the universe began. Hidden inside that darkness sat thousands of galaxies, packed into a patch of sky smaller than a grain of sand held at arm's length. One of them formed just 290 million years after the Big Bang. It carries the mass of 500 million suns, and every model built before this image existed said a galaxy like it should be impossible this early. Tonight we walk through that patch of sky. We will meet the galaxy that broke every rule of when galaxies could exist. We will see how light alone lets scientists measure distance across billions of years. And we will watch record after record fall, as the darkness keeps giving up more than anyone expected. Want these stories early and without ads? Scan

Hey guys! We’re now live on Spotify 🎧 Four decades ago, the American space agency launched a small metal probe with a golden record bolted to its side. Today, it drifts more than 12 billion miles from home, in a place no human instrument has explored: the space between the stars. In 2018, Voyager 2 crossed an invisible wall at the edge of our solar system and entered interstellar space. What it found broke the models scientists had trusted for decades. The plasma should have thinned to nearly nothing. Instead it grew thicker, denser than anything predicted. The magnetic field, the one Voyager was supposed to leave behind, still points the same way it did inside the solar system's bubble, as if the sun's grip reaches further than anyone imagined. Tonight we follow Voyager 2 past that border, into a region where the rules of our solar system stop making sense. Before we start, a quick word.

Hey guys! We’re now live on Spotify 🎧 Somewhere in the universe, a civilization just sent its final message. It might be crossing space right now, and we could receive it in 1,000 years, long after everyone who sent it is gone. Scientists call this the Fermi paradox: if life is common, where is everybody? One unsettling answer: intelligent life might not survive long enough to be found. Every civilization could be born, grow, reach for the stars, and vanish, all in a cosmic blink. Tonight we travel across dying stars, extinct alien empires, and the eerie silence that fills the space between them. We visit worlds where oceans turned to acid, planets whose suns exploded before anyone could escape, and the terrifying math behind civilizational collapse. 🎧 Listen ad-free and get new episodes early on Spotify: link in the description.

Hey guys! We’re now live on Spotify 🎧 Space does not get safer the farther you travel. It gets more violent, and the danger grows with every mile. 600 million miles out, gravity can rip a star apart, thread by thread, and swallow the pieces whole. Push further, and you find deserts of empty space so wide that light takes billions of years to cross them. Push further still, and time itself starts to slow down, then stop. We are traveling through 33 of the most extreme places space has to offer. You will watch a star die in slow motion. You will see what waits inside a black hole's event horizon. You will learn what happens when the entire universe finally goes dark. Before we begin, scan the QR code on your screen, or press the link in the description below. It takes you straight to our Spotify. Watch or listen to these episodes early, and completely free of ads. This part of the universe shows no mercy. Prepare yourself. We go deeper than you have ever gone before.
