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.
