Neil deGrasse Tyson Explains Horsepower
What is horsepower? On this explainer, Neil deGrasse Tyson and comic co-host Chuck Nice break down what horsepower means a unit of measure, and where it comes from. Could we measure explosions in terms of Death Stars?
We hop in our horseless carriages and take a ride down what it means for something to have horsepower. We break down engines and the different metrics used to measure their power. What about watts? How much horsepower does a NASA shuttle rocket engine have? What would it take to get millions of horses to run fast enough to get into orbit? We discuss how the power of atomic bombs and hydrogen bombs are quantified. Exploding horses? Death Stars? All that and more, on another StarTalk explainer!

Can YOU Fix Climate Change?
Never before in human history have we been richer, more advanced or powerful. And yet we feel overwhelmed in the face of rapid climate change. It seems simple on the surface. Greenhouse gases trap energy from the Sun and transfer it to our atmosphere. This leads to warmer winters, harsher summers. Dry places become drier and wet places wetter. Countless ecosystems will die while the rising oceans swallow coasts and the cities we build on them.
So why don’t we just like… prevent all of that? Well, it’s complicated.
