Northern Lights: Earth’s Signal From the Sun | Cosmic Vistas 205+206

More than just a gorgeous cosmic spectacle, the northern lights reveal truths about the makeup of our planet and our sun, and they may even hint at the possibility of life on other planets.

Our understanding of the cosmos is limited not only by what we can see, but by the amount of time we have to see it. Fortunately, computer simulations are helping us see how galaxies interact over millions of years.

Would Interstellar Dust Destroy A Fast Spaceship?

Interstellar dust is a real threat to starships, but is it a dealbreaker? We look at speed, impact energy, and clever shielding.

Do You Believe in Climate Change? | Mutant Weather 101+102

A warmer planet is creating drier conditions and increasing lightening activity – this means more fuel AND ignition – causing catastrophic wildfires and other anomalies like firenadoes. The trend is showing more megafires and a longer fire season, in some cases making wildfires a year-round concern. Large wildfires are also burning in unusual places such as the Arctic Circle. This episode follows recent megastorm events in California and Alberta, Canada

Climate change means warmer ocean temperatures and higher sea levels. This, in turn, is intensifying and strengthening hurricanes and tropical cyclones. Some experts believe it’s time to add a category 6 to the Saffir-Simpson hurricane wind scale. This episode follows the recent Mexico Beach, Florida and Houston, Texas hurricanes.
