This video takes viewers on a 20-year journey to the boundaries of the universe, exploring the huge distances and extreme temperatures involved. The journey is so far that it would take 8 minutes to realize that something was wrong if the flight were to suddenly stop. The video discusses the possibility that there is life on Mars, and that recent activity at a nearby volcano could be indicative of life there. If true, this would be a major discovery as it would mean that life is more widespread than previously thought.

00:00:00 National Geographic videos explore different aspects of the universe, including the origins of the universe and the dangers of space. This video discusses how close our planet is to being hit by a large asteroid, and how humans are trying to find a way to avoid this by exploring space.
00:05:00 A sonda solar venesa express reports that the planet's atmosphere is full of deadly sulfur dioxide, and that the planet is likely headed for a fiery end. Venus is a dangerous deity with an air poisonous to humans, an intense heat, and a pressure that would crush a human. If humans stayed on the planet for too long, they would die from asphyxiation, incineration, and injury.
00:10:00 This video takes viewers on a 20-year journey to the boundaries of the universe, exploring the huge distances and extreme temperatures involved. The journey is so far that it would take 8 minutes to realize that something was wrong if the flight were to suddenly stop. The vastness of the universe is awe-inspiring, and even though it's so heavy, gravity controls everything in the Solar System. However, when close to Earth, we see a familiar family of objects in the sky: a turbulent cloud of gas and dust called the Milky Way. The temperature of the sun's core is estimated at 25 million degrees Celsius, and it must be incredibly hot inside – possibly hot enough to trigger a nuclear reaction that would create energy equivalent to humanity's entire output. At home, we see light as we feel it and experience heat. But close to the sun, there's nothing comforting: it's full of electric and magnetic activity that blasts out in vast circles of gas and dust called protuberances. Each one releases even more energy than 10 million volcanoes could produce. Below the protuberances, layers of colder material can be seen. These are the sun's photosphere, which is about 5,500 degrees Celsius. Above that
00:15:00 The video discusses the possibility that there is life on Mars, and that recent activity at a nearby volcano could be indicative of life there. If true, this would be a major discovery as it would mean that life is more widespread than previously thought.
00:20:00 This video explores how asteroids impact the Earth, and how they may have helped create our planet. By dating the rocks found on Earth, we can learn that our solar system was created 4 million years ago. These rocks are evidence of our planet's birth, and could be the birthplace of all life on Earth. If this is true, then we all have Martian blood in us.
00:25:00 The video discusses how something must have prevented a powerful event from happening, as Jupiter, a planet much larger than Earth, affects the gravity of its neighbors and prevents asteroids from forming into a planet. It is now an impressive sight, but up close it may not be what it seems. This colossal planet is almost all gas, and if you updated the video here we would sink into its layers, perhaps never finding solid ground. Jupiter's beauty is the product of extreme violence, as it orbits at an incredible speed and generates wind speeds of hundreds of kilometers per hour, shaping clouds into spiral whirlwinds and this legendary great red spot, the largest and most violent storm in the solar system at least three times larger than Earth has been raging for 300 years. At this moment, we need a safe refuge, and fortunately, there is one nearby. Far away, in space, is something almost familiar. It's Europe, frozen in time. And maybe, like in the Arctic, this ice is floating on water. Europe is floating in water, and Europa is the place where we are heading in our magical journey to the limits of the universe. So far, it has turned into a desperate flight. We need to keep believing that somewhere among the dangers we call it life,
00:30:00 The video shows the Cassini spacecraft flying over Saturn's moon Titan, which is covered in ice and has a very cold atmosphere. One of the mysteries of Saturn is what happened to its moon Titan, which is now mostly a frozen wasteland. The spacecraft is looking for evidence of life on Titan, which may be difficult considering the cold conditions.
00:35:00 This video, National Geographic's "Viaje a los límites del Universo," explores the vast unknowns of the universe, including the boundaries of our own solar system. To understand the universe, we must explore its limits, and one way to do that is to jump out of sight from Earth. For centuries, we've been on the edges of our solar system, unknown to most of history. Here, on the edge of our solar system, we feel small and alone. But look beyond this point and we see a vast universe filled with strange and mysterious objects. Just a few kilometers away, Neptune's moon Triton is in an opposing orbit, constantly pulling the gas-giant planet back and forth like a yo-yo. Beyond Neptune is a vast region of space where only a few probes have ever ventured. And beyond that is something even more mysterious: the cosmic microwave background radiation. This radiation is the fingerprint of the universe when it was hot, billions of years ago. It's like diving deep into an ocean and coming up to the surface again, only to find that the sea has turned into a storm. It's strange and unsettling to feel so close to all of this, and yet we're always moving away from it
00:40:00 The video discusses the distant object, known as the "Great Wall of Ice", which was discovered in 2003. The wall is located at 16,000 million kilometers from Earth, or 8 billion kilometers from the Sun. It is made up of thousands of icebergs, and it takes 10,000 years for it to make one full orbit around the Sun. Beyond the wall is something even more mysterious: the universe. The video talks about how Voyager 1 has taken images of planets and their moons, and has sent messages back to Earth. It also mentions the Alpha Centauri star system, which has three stars orbiting around each other. These stars are so far away that they are only visible with a telescope. Finally, the video talks about the universe beyond our solar system.
00:45:00 This video discusses the immense distances within the universe, and how 40 million kilometers corresponds to 4 years of light distance from Earth. It is a crazy idea to think about distances that are almost beyond comprehension, and there may be stranger things waiting ahead that we still don't understand. A fascinating world awaits us at the limits of the universe, 10 years away from Earth at the most. There is an Epsilon Eridani star within 10 light years of Earth, and extraordinary rings of dust and ice surrounding it. Somewhere out there are planets forming from discarded materials, and possibly even advanced civilizations. However, we may never be able to find them, as future generations may be able to communicate across these vast distances. We can only speculate about what may be out there, and live our parallel lives ignorant of one another, unless there has been life and it has disappeared. This is the problem with comets - they are both creators and destroyers, like the dinosaurs had to learn the hard way 65 million years ago. This is the needle in the cosmic haystack, and we are very close to finding a habitable system like ours, but we would find it by lucky chance. There may be hundreds of million more solar systems like ours out there, or none at all.
00:50:00 National Geographic discusses how, in the 1990s, they discovered a new kind of star, known as a "velar fon." This star is so close to its sun that it's a miracle that humanity discovered it. The problem is that we can't see planets that are very distant, because they're obscured by the brightness of their nearby stars. However, planets orbiting close to their stars exert a tiny gravitational force on those stars, if we measure these tiny movements at billions of kilometers, we'll be able to prove that they exist. This is how we discovered "veleer fon" in the 1990s. By tuning in to this star, we were able to detect television signals from the Olympic games in Berlin. Strangely, one of the stars in the sky seemed to be blinking, as if it was passing in front of the other. Even more strangely, when one of these stars gets close to the other, it begins to suck the gravity off of it. At almost 100 light years away, it's still incredibly strange to hear one of the very first transmissions from radio. And then, after that, there's complete silence from here on out. It's as if the Earth never existed. The beings that can live
00:55:00 National Geographic discusses how stars are born and die, and how the elements necessary for life were created in the process. The video also shows how the end of the universe is approaching, and how the death of a star will mark the end of life on Earth.

01:00:00 - 01:30:00

This video from National Geographic explores the universe, from its origins to its future. It takes viewers on a journey to the limits of the universe, exploring the patterns of order that exist in this chaos. There is a recurring cycle of birth and death, creation and destruction, which is woven through the vast space that connects each galaxy. There are potentially billions of stars in the universe each with billions of planets, and possibly even more stars that have already died.

01:00:00 National Geographic explains the origins of the universe, including the explosion of a supernova that created the black hole at the center of the galaxy. They also discuss the dangers of coming too close to a black hole, which poses a threat even more deadly than the sun.
01:05:00 In this video, National Geographic describes the phenomenon of a collapsing star, and how we are currently witnessing its final stages. The video also features footage of a larger, more dangerous star that is on the verge of exploding. In order to escape, we must venture further into the boundaries of our galaxy. However, it is difficult to abandon beautiful things like this star when it is so close to us.
01:10:00 The video features footage of stars and galaxies, and explains that despite not finding evidence of extraterrestrial life, it is still possible that there are other civilizations out there. The mathematics behind estimating the number of other civilizations in the universe is staggering, and suggests that there may be millions of them.
01:15:00 The video showcases the vastness of the universe by traveling to its limits. Outside of our galaxy, there is no visible horizon, and even more distant galaxies are located millions of light years away. Remnants of broken galaxies are scattered by the immense gravitational force of the galactic plane. Even this "perfect" void is not completely empty; there are thin gas bridges that remain after the dust and gas is scattered by the nothingness. Something mysterious and invisible holds these stars and galaxies together, making up the majority of the universe's matter. If dark matter exists, this means that there is nothing similar to space vacuum even here. We see ourselves surrounded by matter only due to the strange gravitational attraction it has over galaxies. The Large Magellanic Cloud, which is at a distance of 6 million million years in space and 160 million years from the galactic plane, is moving through space at a speed of almost a million kilometers per hour. this galaxy could be flying through space, but something keeps it here. This something is invisible and powerful, matter or dark matter. Colored stars are like strands of pearls, a sphere of fire expanding through what must have been a great explosion. It was so bright that when the light of the explosion reached Earth in 1987,
01:20:00 National Geographic explores the vast universe, from its origins to its future. This video takes viewers on a journey to the limits of the universe, exploring the patterns of order that exist in this chaos. There is a recurring cycle of birth and death, creation and destruction, which is woven through the vast space that connects each galaxy. There are potentially billions of stars in the universe each with billions of planets, and possibly even more stars that have already died. Our journey into the past takes us further back than when dinosaurs roamed the earth, to the moment when early creatures began to climb onto the land. We continue to journey back in time, beyond the moment when dinosaurs were wiped out, to the moment when the first creatures set foot in space. We reach the limits of our understanding as we explore the depths of the black heart of the beast, a dark hole so massive it weighs millions of suns, and consumes stars whole. And in the end, we glimpse the ultimate danger looming in the universe--something so powerful and awe-inspiring it must be incredibly dangerous. We must travel further into space if we want to discover the last corner of the universe known to us, and face the dangers that await us there.
01:25:00 In this video, National Geographic takes viewers on a journey to the limits of the universe, exploring how galaxies evolved and how the universe began. It shows how, billions of years ago, the same moment that created our universe was also the most violent and creative moment in its history. Today, the light from the big-bang still stretches out like a radio wave. We see this light in our televisions, even though we may not be watching it. National Geographic then takes us on a journey through time, showing how we are travelling on an expanding wave. Everything we've seen on this journey is courtesy of the explosions that created stars, planets, and galaxies.
01:30:00 In the video, National Geographic explores the idea of our universe being one big, interconnected mess of waste. They travel through our galaxy, our solar system, and even beyond to explore the origins of the universe and what might happen in the future. While exploring, they discuss the idea of a "multiverse" in which our universe may be only one of many, and in which some of our descendants may find a new home. If they're lucky, they'll live in a universe where the sun still shines, and they'll have a new home to call their own.
