Episode 290 - The strange chemistry of exoplanets from their cores to atmospheres

Exoplanets are home to some extremely out of this world chemistry. From raining diamonds, to gaseous iron and titanium, even to secret supplies of water. If we want to understand just how unique our place in the universe is, we can try and replicate the odd conditions of exoplanets right here on earth.    References Peter M.
