Cities are one of our greatest inventions, they bring us together and drive wealth, but as more of us flock to live and work in them, we need to find ways to make them greener, more sustainable and efficient places to live. Physicist Dr Niraj Lal explores some of the engineering solutions driving change. To see how we’ll keep our growing population moving he visits the construction site of the largest public transport system ever undertaken in Australia and discovers how engineers are finding ways to replace concrete - one of the biggest CO2 emitters in the world - with greener alternatives.

Is a zombie apocalypse simply a concept of fiction or could an infectious disease actually turn humanity into a race of vicious monsters? The truth just might shock you!
Astrophysicist Professor Tamara Davis explores the impact asteroids have had on our planet and discovers that they may hold the key to one of the greatest scientific mysteries of all - how life began. In the Northern Territory, Tamara sees first-hand the destructive power of an asteroid - the gaping 25 kilometre wide Tnorala crater. Keeping an eye on current threats are teams at the Siding Spring Observatory, where Tamara observes one of the thousands of potentially hazardous asteroids rocketing through space. Tamara uncovers the story of Victoria's Murchison meteorite, which contains complex organic compounds that scientists are experimenting with in New Zealand, to determine if a meteorite could have kickstarted life on earth.
From dawn to dusk, encounter monster volcanoes, ancient lakes, alien ice-worlds, and spacecraft crash sites on this orbit around the Red Planet.
Could there be multiple versions of reality? Scientists explore the possibility that the fate of the universe may depend on hidden cosmic twins.
Gold finally meets the mysterious Chlorine. They try bonding with no success. Carbon and his heavies arrive on the scene. Gold and Chlorine are able to escape, but wait - Chlorine has ionically bonded with Potassium.
Professor Kaitlin Kratter shows us how extreme Jupiter is. She's come to a quarry to measure out each planet's mass with rocks, starting with the smallest. Mercury is a single kilogram, and the Earth is 17. But Jupiter is on another scale entirely. It's seven tonnes, that's two and a half times the mass of all the other planets combined. On Kaitlin's scale it's not a pile of rocks, it's the truck delivering them.
This special takes viewers behind the scenes to show the incredible lengths the crews go to as they capture memorable scenes from the hugely successful natural history series Planet Earth II.
