The Earth seems like a safe place, most of the time. But we have evidence of terrible catastrophes in the ancient past. Times when almost all life on Earth was wiped out in a geologic instant. What could have caused so much devastation? And will something like this happen again?

Ep. 219: Planck Mission
Another mission named after a famous physicist. This time we’re looking at the Planck mission, designed to study the Cosmic Microwave Background Radiation over the entire sky. Like the previous WMAP mission, this will help astronomers understand the first moments after the Big Bang.
Ep. 218: Max Planck
It’s time for another action-packed double episode, where we meet a man and his mission. This time around its German physicist Max Planck, considered to be the father of quantum theory – he was later granted a Nobel Prize for just that discovery. Let’s take a trip back just over 100 years to learn about the man who changed our understanding of the very small.
Ep. 217: Stellar Classification
Have you ever heard an astronomer utter these words? Oh be a fine girl and kiss me. They’re not being romantic, they’re trying to remember the different ways to organize stars, as detailed nicely on a Hertzsprung–Russell diagram. Let’s learn what all those letters mean, and what differentiates a type-O star from a type-G.
