How the Universe Works ~ Supernovas

Today on Far Future Horizons we present another exciting episode from the acclaimed documentary series How the Universe Works.

In this installment of How the Universe Works we explore the cataclysmic death of massive supergiant stars. These explosions are known as Supernovas and they play an important role in Cosmic Evolution.

A supernova is an explosion of a massive supergiant star. It may shine with the brightness of 10 billion suns. The total energy output may be 1044 joules, as much as the total output of the sun during its 10 billion year lifetime. The likely scenario is that fusion proceeds to build up a core of iron.

This episode of How the Universe Works can be purchased direct from Amazon's Instant Video.
