The Universe Season 2, Episode 9: Supernovas
A stellar explosion, the supernova is the sensational death of a star. It can shine as bright as 100 billion suns and radiate as much energy as the Sun would emit over 10 billion years. Jets of high-energy light and matter are propelled into space and can cause massive gamma ray bursts and emit intense X-ray radiation for thousands of years. Astronomers believe that this process creates the very building blocks of planets, people and plants. Watch The Universe Season 2, Episode 9 Supernovas in HD free online.

The Milky Way
We used to think that Earth was at the center of the universe, but now we know we're not even at the center of our own galaxy. Countless wonders exist between where earth is situated and the massive black hole at the galactic center of our solar system. Within the Milky Way can be found the debris of old, dying stars fueling the birth of new stars and at the galactic center hypervelocity stars get catapulted clear beyond the Milky Way's outer rim at unimaginable speeds. Come along for a guided tour of 100,000 light-year-wide family of stars and stellar phenomena we call The Milky Way.

Dark Matter
Scientists have no idea what it is, but Dark Matter and Dark Energy make up 96% of the Universe. Dark Matter is everywhere. It passes through everything we know on earth at billions of particles every second, yet no one has ever gotten a direct detection of this mysterious dark substance. An even more bewildering force is Dark Energy, which is rapidly pushing apart our Universe. Discovered only ten years ago, scientists are struggling to comprehend its unusual characteristics and answer the ultimate question; what is the fate of our Universe?

Space Travel
When man finally broke free of the Earth's gravitational pull the dream of traveling to other planets became a reality. Today scientists are proposing a bizarre array of technologies in the hope of traveling faster through space, from space craft sporting sails that catch laser beams, to propulsion engines powered by a bizarre entity known as anti-matter.

Cosmic Apocalypse
The Universe as we know it is condemned to death. Space, matter and even time will one day cease to exist and there's nothing we can do about it. Harsh realities are revealed about the future of our Universe; it may collapse and burn or it might be gripped by a galactic ice age. Either of these scenarios might be a long way off. However, our Universe could suddenly be destroyed by a "random quantum fluctuation", a bubble of destruction that can obliterate the entire cosmos in the blink of an eye. No matter how it ends, life in our Universe is doomed.
