The highs and lows of our nearest star, the Sun
6 December 2011
Tuesday 29 November 2011
Dr Lucie Green (UCL Mullard Space Science Laboratory)
There is more to the Sun than meets the eye. Observations from spacecraft have, over the last 50 years, revealed a dynamic and active behaviour to our Sun that cannot be seen from the Earth. Recent reports have given seemingly contradictory information that the Sun is entering a period of high activity but also that in the coming decades the overall solar activity will significantly decline, and could stop altogether. This talk discusses the science behind this activity, or lack of, and show the latest images of the Sun taken by telescopes in space provided by the European, American and Japanese space agencies.
