This Interstellar Comet Formed Near Absolute Zero Before It Ever Reached Us

Hey guys! We’re now live on Spotify 🎧 Right now, you are flying around the Sun at about 67,000 miles per hour. You feel nothing. Yet that speed is the reason the Sun is so hard to reach. Here is the strange part. We sent a spacecraft 3 billion miles to Pluto in under 10 years. But falling into the Sun, our own star, takes more energy than leaving the solar system entirely. And flying over the top of the Sun? For most of the space age, it seemed close to impossible. Every planet, every probe, every rocket we launch is trapped in one flat disk around the star. Climbing out of that disk is one of the hardest moves in space travel. Tonight, we ride with a probe that dove through the Sun's burning outer air. We swing around Venus again and again. We use giant Jupiter as a slingshot. And we finally see the Sun's hidden poles for the very first time. If you want to hear our videos earlier and without ads, come find us on Spotify.

Hey guys! We’re now live on Spotify 🎧 Almost every deep image from the James Webb Space Telescope hides the same strange thing. A tiny red dot. 1 pixel wide. Shining as bright as an entire galaxy. These dots come from the first 1.5 billion years of the universe. They are everywhere. For 3 years, astronomers have argued about what they are. First, they looked like giant galaxies, far too big for their age. Then they looked like hungry black holes. But those black holes stayed quiet. Almost no X-rays. Almost no flicker. Now a bold new theory has split the field down the middle. What if each dot is a single, swollen star, stretching far past the orbit of Pluto, with a black hole burning at its heart? We will visit an object called The Cliff, which defeated every model scientists tried. We will weigh a hidden black hole through a natural magnifying glass made of galaxies. And we will follow the red dots as they seem to vanish from the universe. If you want to watch or listen

Hey guys! We’re now live on Spotify 🎧 Right now, 14 million light-years from Earth, a giant cloud hangs in the dark. It holds enough hydrogen gas to build 1 million suns. And as far as our sharpest telescopes can tell, it has zero stars. Astronomers aimed Hubble straight at its heart. They found empty space. Every galaxy we know started as a pool of gas. Then the gas lit up. Stars were born. Worlds followed. Scientists believe this cloud froze at that very first step, billions of years ago, and stayed frozen. Something heavy holds it together. Something invisible. This hidden mass outweighs the gas about 5,000 times. Scientists call it dark matter. And it makes up most of the matter in the universe. Today, we follow the trail. We visit spinning galaxies that exposed this hidden mass. We climb to a giant radio dish in the mountains of China. We weigh a ghost. And we meet a second galaxy that seems 99.9% invisible.

Hey guys! We’re now live on Spotify 🎧 Pluto sits about 3.7 billion miles from the Sun. The fastest spacecraft we ever launched needed 9 and a half years to get there. And it never stopped. It flew past at more than 30,000 miles per hour. It snapped its photos. Then it was gone. So what happens if you want to go there, land, and come back home? The answer is brutal. With the rockets we have today, the cheapest road takes about 45 years. One way. Tonight, we build that trip piece by piece. We will swing past Jupiter for a free push. We will pack food, water, and air for a journey longer than most careers. We will face invisible radiation, a Sun that shrinks into a bright star, and a frozen world near 400 degrees below zero Fahrenheit. Then we will try to come home. 🎧 Our videos are on Spotify too.

Hey guys! We’re now live on Spotify 🎧 Picture a circle of light so perfect it looks painted onto the sky. It is hanging in deep space right now, completely real. You are looking at gravity itself, bending light into a shape it should never make. The James Webb Space Telescope caught this ring while scanning distant galaxy clusters. Its light traveled 21 billion light years to reach us, the most distant object of its kind ever recorded. A shape this exact needs near impossible alignment. Two galaxies and Earth, lined up across millions of light years. Today we visit that ring, and a few more like it. One was found by an amateur, sorting through public Webb data at home. Another hides a galaxy far denser than it should be. One more comes from a survey of 182 galaxy clusters, watched across 8 billion years.

Hey guys! We’re now live on Spotify 🎧 Title: Why a Return Trip From Mercury Might Be Physically Impossible Inspired by: You leave Mercury. But can you ever come home? Scientists are not sure you can. Mercury sits so close to the sun that gravity there works like a trap, not a ladder. Reaching this world already takes more fuel than a trip to Jupiter. Leaving it could take even more. In this series, we uncover the real physics that make Mercury a one way risk. We look at the sun's crushing gravity well, the heat that can melt metal, and the fuel math that breaks every plan. We follow the spacecraft that barely survived getting close. And we ask the biggest question of all. Could a human crew ever fly home from Mercury? Prepare yourselves. This is the planet that might not let you leave. Before we start, scan the QR code on your screen, or tap the link in the description. That takes you straight to our show on Spotify.
