Show Notes
The weight on that box of breakfast cereal ultimately traces back to "le grand K", a metal sphere in a vault in Paris, a wonderfully archaic standard for how much stuff makes a kilogram. We'll talk about the efforts to update that standard, the next Kuiper Belt Object to be explored by the New Horizons spacecraft, eclipses and occultations, and of course Zombies. Join the astroquarks for the latest astro-news, nerd news, and this episode's trivia about the length of the month!
