00:00:00 - Asteroid Alert: Earth is at constant risk from asteroids and other space debris. The vast majority of these impacts are minimal and have almost no effect on the planet. However over the course of its life, earth has been hit with asteroids that caused such major damage that it changed the planet for centuries to come. How do we know when the next major impact could be? Is there anything we can do to stop it?

00:45:08 - Saturn’s Secrets: From 2004 to 2017, the Cassini-Huygens spacecraft launched in 1997 orbited Saturn. It sent back a wealth of knowledge about this elusive planet, including the secrets of its rings and its largest moon, Titan.

01:30:14 - Space Weather: The earth's magnetic field is vitally important to not only the planet, but the life on the planet as well. This field provides the perfect conditions to allow life to thrive on earth as well as protect us from dangerous space debris. But what would life on earth be like in the future when this field gets dangerously weak?

02:15:32 - Solar Storm: The power of the sun is equal parts awe-inspiring and terrifying. Despite being 147.7 million kilometers away from it, Earth still feels the effects of it at full force. One example of this is solar storms, where explosions on the surface of the sun sends radiation flying towards earth.

03:00:51 - Great Lakes: The Great Lakes are an incredible natural resource. 1/5th of the world's drinking water are stored in them and they hold enough water to flood continental America 9 feet deep. How did such vast bodies form on Earth? And how are rising water levels affecting these Great Lakes?
