Key Info
  • The colours of stars
  • Duration: 04:50
  • Even with the naked eye, not all stars appear white. Mark Thompson explains how their different colours give us an insight into how the stars live and die. The colour tells us about the temperature of a star: red being cool and blue/ white being very hot. This will determine how quickly they will burn their fuel and therefore how long they will live. First broadcast on 'Stargazing Live' on BBC Two in January 2013.
