How the Universe Works Season 11

 

The Moons of Saturn

   2023    Science
The magnificent ringed planet Saturn, along with its more than 80 moons, forms the most dynamic planetary system in our neighborhood. With underground oceans and protective magnetic fields, experts are exploring how this collective of satellites has the potential to rewrite the rules of the Solar System.
The closer that we look, the more we see these extraordinary moons like worlds of their own -- so dynamic, so Earth-like. Almost a billion miles from the Sun, these icy worlds could be home for Life 2.0. The moons of Saturn offer possibly the best chance of finding extraterrestrial life in our solar system. With each new mission, we get closer to unraveling the mysteries of Saturn's moons.

A Robot Guide to Mars

   2023    Science
Mars is infested with robots, orbiting the planet and roaming the Martian surface on a mission to uncover its secrets; now, Perseverance joins this dedicated group of machines to uncover if there is, or was ever, life on the Red Planet.
Our neighbor, Mars, fascinates us. It's a planet that is similar to Earth but with some big differences. Mars is rusty, dusty, frigid, and frozen. Past missions suggest that Mars was once a very different world. The Mars we see today has completely changed from the Mars of a few billion years ago. Without a time machine to explore ancient Mars, we employ a team of high-tech robot investigators, an entire fleet of robotic spacecraft exploring the planet. Working together, they dig into Mars's past to answer the ultimate question -- did Mars once have life?

The Most Violent Event in the Universe

   2023    Science
The collision of two supermassive black holes is the most violent event that can occur in the universe; experts explore where a black hole's energy originates and what really happens when the two most powerful objects in the cosmos clash. It is a soul-chilling, mind-crushing amount of energy. Take your ringside seat to the ultimate fight of the universe. Get ready for the final of the cosmos heavyweight championship.

Countdown to Catastrophe

   2023    Science
November 4, 2029. We face a countdown to catastrophe. A giant asteroid hurtles towards Earth at 40,000 mph. It's heading straight for the eastern seaboard of the United States. The space rock could wipe out an entire city and cause widespread devastation. Can Earth survive? Now, experts confront the story of this fictional asteroid event to determine what could happen, and how it might be stopped.

Solar System Special

   2023    Science
New discoveries have rewritten the history of our solar system, revealing a complex and violent story that begins with the birth of our Sun from the debris of a massive galactic collision, to its eventual fate as a lone zombie star.
It is a dramatic history of elegant beauty and extreme violence. The inner solar system was like a congested highway. Planets crossing lanes, frequent collisions. There were a lot of planets that could have made it but didn't, and we just happen to be one of the lucky ones that did. The players in our solar system's story are more tangled up than we ever imagined. Without all of these things interplaying, the Earth wouldn't have the stable environment that we have today, and life wouldn't be able to exist.
