For anyone who has wondered, “Where Did Life Come From, and Where Can It Go?” Where are the fungi from, Cotton Eye Joe? Long before they helped craft Earth’s first soils, fungi may have traveled the universe in rudimentary spaceships made of rock. Izzie plunges into the science of sci-fi mycology, breaking down the impossible mission of microbes in space and laying out some of the evidence for – and against – the idea that we Earthlings are not alone. Highlights include fungi stuck onto the ISS and bacteria being shot out of a cannon.
