    Is Anyone Out There? (Season 2)


The Known Universe gives vital insights into a world we thought we knew. Using an unprecedented combination of the most current scientific information, mind-blowing computer graphics and relatable analogies and comparisons, the things we thought we learned in Science 101 will finally become accessible and understood.


  • Surviving Outer Space


    The human body thrives on the welcome confines of Earth…but in space, survival becomes a tense, daily challenge. Micro-gravity's effects on daily human activity, from eating to sleep to sex, are just beginning to be understood. But these are only the start of our problems - we'll also explore how the vacuum of space and it's near-zero pressure can kill us within minutes, if not seconds. And the ultimate space executioner may be the ever-present dangers of solar radiation. How will we overcome the odds and survive space.

  • Treasure Hunt


    For ages, mankind has been obsessed with finding treasure, from mining gold and other precious metals to the allure of diamonds buried deep underground. We'll see that as our technology leads us further into space, we're discovering new frontiers - asteroids containing more metal than we've ever mined on Earth, and planets like Neptune that may have vast liquid diamond oceans. And our very definition of treasure itself will change, as we hunt for new energy sources and the most elusive and important treasure necessary for our survival - water.

  • Most Powerful Stars


    Our Sun is a tremendous source of energy and danger for our planet, but it has nothing on the stars that lie beyond our own tiny solar system. The biggest star known to man is a hyper red giant…yet size doesn't always equal power when we see how smaller, blue super-giants burn many times hotter. We'll explore how a star becomes even more powerful in its violent supernova death, and how the most intense place in the universe may not be a star at all…but a black hole.

  • Extreme Space Tech


    Humans have come to recognize Earth as an environment where we are in control. We're continually creating technologies that get bigger, faster, and make us more interconnected. In this episode of KNOWN UNIVERSE we'll explore how science is re-thinking the physics of the universe to take everything from basic household items and vehicles to our most advanced technologies here on Earth and transform them for use in space.

  • Biggest Cosmic Blasts


    Eruptions are not unique to our small planet - in fact, exploding is truly a universal language. Our solar system is home to an incredible amount of it - from Venus' entire surface being remade from mile-deep lava to Jupiter's moon, Io, which is the most volcanically active place we know. And we're discovering more about these explosive forces every day, in cold ice-volcanoes on Saturn's moon Enceladus, in the depths of a black hole located in the Virgo constellation, and in huge subterranean lava tubes beneath the surface of Mars, the home to the largest volcano in the solar system, the Olympus Mons.

  • Construction Zone


    Engineering in space represents the future of human civilization but also poses some of our greatest technical difficulties. Building in zero-G is like constructing a ship, at sea…while it's moving. We'll travel to NASA's tool lab and see the gear we need to build in this challenging environment, from high tech wrenches and hammers to the ultimate robotic handyman, Robonaut. We'll build a skyscraper on the moon and see what it takes to protect our cosmic constructions from being destroyed by particles no bigger than a pea, traveling at nearly 18,000 miles an hour. Finally we'll explore the ultimate cosmic big build, giant spinning space stations,...

  • Escaping Earth


    We've landed on the moon, and launched probes to study planets hundreds of millions of miles away. But when it comes to space travel, we're just babes in the woods. Of the hundreds of launches we've made into space, only a handful have even left Earth's gravity. So what's the problem? Well, for one, it's a huge challenge just getting off the planet. If you want to get into space you have to fly fast and high. Find out just how tough and complicated future space travel can be on Known Universe Escaping Earth.

  • End of The World


    For every beginning there is an end and every end, a new beginning. This is true for humans and all life as we know it on Earth. But it's also true for everything in the Known Universe - from asteroids, comets and moons, to planets, stars…even galaxies. And this cycle of life and death is a lot bigger, and a lot more complex, than you might think. Join us for an epic tale of death and rebirth on Known Universe.
