Brian Cox and Robin Ince start a new series from Sydney, Australia. They are joined by astrophysicists Kirsten Banks and Devika Kamath and comedian Ross Noble as they discuss how different the night sky looks from the southern hemisphere. They hear stories of how different cultures have always used constellations in the sky to help navigate life down here, on planet Earth. They find out how just one point of light can tell you exactly what a star is made of and why this can be the key to understanding the future of our galaxy.
