This StarTalk All-Stars show that I was lucky enough to host is all about water in the Solar System, entitled ‘Searching for Space Water‘. If you’re in my home country, the UK, then you probably know where all of the Solar System’s water is; hee hee, it’s all around you most of the time. However, if you’re in California, where I’m living at the moment, then you’ll more likely be questioning where all the water went (seriously, no rain since April??!). Anyway, in this episode I investigate where the Solar System’s water is and I’m joined by the fascinating Lindy Elkins-Tanton, director of the School of Earth and Space Exploration at Arizona State University and probably the most water-enthusiastic person I’ve ever met. In the style of Cosmic Queries we have a bunch of questions to tackle sent in by StarTalk fans from all over the world. Lindy and I had no idea what the questions would be in advance and it was the job of comedian and co-host Chuck Nice to reveal the questions to us live. Luckily Lindy was on hand to help me out with answering some of these questions which took us all the way from our own Earth to moons around other planets. It was a fantastic fun-filled discussion; I hope you’ll enjoy listening to the show as much we enjoyed recording it.
