How Long a Round Trip to Pluto Would Actually Take — And Why the Answer Is Brutal

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 🎧 A frozen stranger just crossed our solar system at 137,000 miles per hour. It came from another star. And its ice holds a message older than the Sun. In 2025, a telescope in Chile spotted it near Jupiter. It was only the 3rd visitor from another star ever found. The biggest telescopes on Earth turned to look. They studied its gas. They measured its water. What they found stunned them. Scientists confirmed that its water carries 30 times more heavy hydrogen than comets from our own solar system. That chemistry needs brutal cold, about minus 405 degrees Fahrenheit. Barely above absolute zero, the coldest temperature possible. And its carbon hints at something even wilder. The leading theory says this comet may be 12 billion years old. Almost 3 times the age of Earth. Tonight, we follow it backward. Into a dark, frozen nursery around an unknown star. Across billions of years of empty space. Past Mars. Around our Sun. And out again, forever. Before we start, a quick gift for you. Scan

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.

Hey guys! We’re now live on Spotify 🎧 Right now, on the Moon, there's a machine that no one has touched in over 50 years. Apollo 11's landing gear is still standing on the Sea of Tranquility. The footprints from the first human steps are still pressed into the dust beside it. On Earth, wind and rain erase footprints in weeks. But the Moon follows a different rule. The surface barely changes on its own. Every single day, tiny space rocks slam into that site. Radiation from the sun bakes the metal and plastic Neil Armstrong and Buzz Aldrin left behind. Slowly, over decades, this frozen moment in history is changing. Today we're going back to that landing site. We'll show you the newest photos NASA took from 60 miles above it. We'll show you what's cracking, what's fading, and what scientists think will happen to it next. Before we start, here's something quick.
