Season three of this unique and fun science series which gives vital insights into a world we thought we knew.


  • Known Universe 3: 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.
  • Known Universe 3: 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.
  • Known Universe 3: 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.
  • Known Universe 3: 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.
