The Universe (Season 4)

The Universe is a History Channel documentary series exploring the wonders of the universe and the advanced physics concepts in the fields of cosmology, astronomy and astrophysics. The Universe (Season 4) consists of twelve episodes, exploring space disasters, mysteries in our universe. Topics covered in this season three include: death stars, what the Earth would be like without the moon, supernova blasts, ten events that could destroy the planet Earth, and space wars. The series features a mix of historical footage, photographs from space telescopes, and computer-generated graphics, as well as interviews with experts from universities and scientific institutions around the world.

Death Stars

Episode 01 - Death Stars
A look at real life "death stars" that are far worse than the one in Star Wars such as supernovas that unleash massive gamma-ray bursts (GRB) that could eradicate all life for thousands of light years.

Episode 02 - The Day the Moon Was Gone
A look at the importance of our moon and what the Earth would be like without one, such as a four hours of sunlight, pitch-black nights, and the end of complex life forms.

Episode 03 - It Fell from Space
A look at some of the thousands of objects, both natural and man made, that have plummeted to Earth.

Episode 04 - Biggest Blasts
A look at some of the biggest explosions known, from the "Big Bang", to incredible supernova blasts, to the massive impact of the Chicxulub asteroid on the Yucatan Peninsula.

Episode 05 - The Hunt for Ringed Planets
A look at planetary rings, especially those of Saturn where house-sized chunks of ice orbit at 53,000 MPH along a chaotic orbital racetrack; how the rings formed and the dangers they pose to spacecraft.

Episode 06 - 10 Ways to Destroy the Earth
A look at ten events experts envision, (both fun and serious), that could destroy the planet Earth - such as being swallowed up by a microscopic black hole.

Episode 07 - The Search for Cosmic Clusters
A look at star clusters; how all stars within them are formed from the same material and are approximately the same age.

Episode 08 - Space Wars
A look at military concepts to weaponize space; how such systems would work and how effective would they be, such as an idea of telephone pole-sized rods that could be hurtled down from orbit.

Episode 09 - Liquid Universe
A look at places in the solar system where it rains droplets of liquid iron even at hundreds of degrees below zero where there are oceans of liquid methane.

Episode 10 - Pulsars & Quasars
A look at pulsars - tiny objects (only a few miles across) with powerful magnetic fields that spin so fast they appear to blink on and off; and quasars - the remnant cores of ancient galaxies.

Episode 11 - Science Fiction, Science Fact
A look at fantastic technology concepts, once mocked by physicists, that could be just over the horizon, such as teleportation, anti-gravity, and breaking the light speed barrier.

Episode 12 - Extreme Energy
A look at the energy emitted by the universe, from powerful jets ejected by black holes, to the nuclear fury of the sun; and how the universe maintains this energy in perfect balance through the conservation of energy.
