An exploration of the sun and the life cycle of stars.
The Sun: solar physicist Lucie Green reveals her life long fascination with our nearest star, and explains how space telescopes are allowing us to see it in greater detail than ever before. The latest solar missions reveal sunspots, solar flares, and coronal mass ejections, and Lucie explains exactly what effect such violent phenomena can have on our life on Earth. The Life Cycle of Stars: astronomer Tim O’Brien from Jodrell Bank Observatory explains how a star is born, lives and dies. He compares the life of stars like our sun with much more massive stars, which can end their lives by creating supernovae, neutron stars and even black holes.
