Link to How the universe works: 4- Extreme stars documentary
Documentary Description
This programme with tell the story of how stars were engineered by the
Universe and how Stars then went on to engineer everything else in that
very universe. We'll learn how nuclear fusion in the core of these stars
keeps them burning for billions of years and is what powers our nearest
star 'the sun'. They transformed the Universe by spawning further
generations of stars, then planets and eventually the building blocks of
life itself. We will follow the life-cycle of stars from 'red giants'
like our own sun that die leaving beautiful 'planetary nebula', to
massive 'red supergiants' which die young in violent events called
supernovae, creating elements from the gold in our wedding rings to the
iron in our blood.
