Series: How the Universe Works

 

Journey from the Center of the Sun

   2014    Science
How does light escape from the sun? We take a journey from the center of the sun, following the path of light. We witness its fiery birth from in the core, its 430,000 mile battle against gravity and magnetism, and its escape from the solar surface.

Did a Black Hole Build the Milky Way

   2014    Nature
What built the Milky Way? New research might now have the answer, revealing an unlikely hero. At the heart of our galaxy sits a super massive black hole, one of the most destructive objects in the Universe. Could it be our creator?

Our Voyage to the Stars

   2014    Technology
One day, a cosmic disaster will make life on Earth impossible. To survive, we must find a new home amongst the stars. Scientists are already developing new propulsion systems to take us to these distant worlds.

Birth of the Earth

   2012    Science
The Earth was formed by a series of cosmic cataclysms including the most powerful blast in the Universe. Yet amid the turmoil our world was born. Could the same chain of events have created other earths elsewhere, inhabited by creatures like us?

Extreme Orbits - Clockwork and Creation

   2012    Science
Orbits are the dynamics that drive the universe. From the smallest asteroid to the largest super-cluster, everything in the universe is in orbit. We owe our very existence to the stability of earth's orbit — it gave us life and keeps us safe. But we are the freaks. Everywhere else we look we find orbits are chaotic, unstable, and violent. Beyond our solar system we find planets that are blow-torched, stars that eat each other, and black holes that destroy everything in their path. Yet on the very largest scale, orbits are also a creative force. clashing galaxies give birth to new stars and new worlds. on the galactic scale orbits even construct the fabric of the universe itself.
