Episode Synopsis "Lecture 2 - The mystery of the first stars"

Dr Grant Christie MNZM, Research Astronomer, Stardome Observatory The first stars formed when the Universe was less than 2% of its current age. At this early epoch the conditions were very different to those that exist now so exactly how these stars got started and what they were like remains a major unsolved problem in astronomy. Can we probe this far back in time and shed light on how the first stars formed? Recorded at Auckland's Stardome.
