Episode Details

Look up on a clear night and you might see hundreds, or even thousands, of stars. But where did they all come from, and what makes a new star begin to shine?

This week, Isabella from Cammeray asks: How are stars formed? Christie travels into a stellar nursery to discover how gravity gathers enormous clouds of gas and dust, why a growing protostar becomes incredibly hot, and how nuclear fusion turns it into a shining star.

Plus, if stars aren’t really on fire, what produces all that heat and light?
