Ep. 416: Fireballs from the Sky!
Every now and then we look up and see bright fiery balls falling from the sky. Don’t panic, these are just bolides. Sometimes they leave trails, sometimes they explode, and sometimes they survive all the way to the ground.
Ep. 415: Temperature of the Universe
The temperature of the Universe can vary a dramatic amount from the hot cores of stars to the vast cold emptiness of deep space. What’s the temperature of the Universe now, and what will it be in the future?
Ep. 414: Navigating Far
In our last episode, we talked about what it’ll take to navigate across the Solar System. In this episode we scale things up and speculate how future civilizations will navigate to other stars and even other galaxies.
Ep. 413: Navigating Near
It’s hard enough finding your way around planet Earth, but what do you do when you’re trying to find your way around the Solar System? Today we’ll talk about how spacecraft navigate from world to world.
Ep. 412: The Color of the Universe
What color is the Universe? Turns out this isn’t a simple question, and one that scientists have really been unable to answer, until now!
Ep. 411: Science of Sunset Colors
We all enjoy beautiful, multicolored sunsets. But what causes the brilliant oranges, pinks and purples that we see, and why does it change from day to day and season to season?
Ep. 410: Planet 9 Facts and Fiction
The discovery of Planet 9 has caused a wonderful, confusing uproar and a flood of misinformation in the news and social media. We’ll sort out what we actually know, what things just aren’t true, and what things might be possible!
Ep. 409: Spin in the Solar System
The Solar System is a spinny place. Everything’s turning turning. But if you look closely, there are some pretty strange spins going on. Today we talk about how everything started turning, and the factors that still “impact” them today.
Ep. 408: Universe Cannibalism
We’ve talked about stellar cannibalism and galactic cannibalism, but now it’s time to take this concept to its logical extreme – universe cannibalism. In the multiverse theory of physics we live in just one of a vast range of universes which might interact with each other. Let’s look for the evidence.
Ep. 407: Galactic Cannibalism
Remember when we told you that the Universe is a big place, and anything that can go wrong, inevitably does? Today we talk about what happens when galaxies come together. This is particularly pertinent because our Milky Way will collide with Andromeda in the future!
