Episode aired: Sunday 13th March
In the second episode of the series Brian cox explained how we were made from the deep interior of stars. A list of star-stuff known commonly as the periodic table of elements consists of 92 elements that we, the earth, solar system, galaxies and what we can see in the universe is made up of.
Brian used analogies such as when bubbles stick together and even the demolition of a building to explain how the basic elements hydrogen and helium were created at the very beginning of the Universe.
Elements up to iron are created inside stars as they near the end of their lives. The heavier elements such as Gold, Platinum and Zinc are created by stars that undergo cataclysmic explosions called supernova, forming the Earth and ultimately life.
Locations included India, Chile and America. Brian was even playing an old piano in a derelict western-style bar on the outskirts of a disused gold mine in California as he explained how much gold there is on Earth and why it is so rare.
Another really good episode.
