The changing Sun

Museum scientists are studying data from ground and satellite-based instruments to better understand current solar activity. This data complements meteorite geochemistry, geological proxy data and historical observations in the interpretation of climate change. 

Museum scientists Prof Ken Phillips and Dr Claudio Vita-Finzi are studying:

Historical observations of solar behaviour and geomagnetism complement the analysis of spacecraft data.

Spectroscopic data is used to determine element abundances, which are then compared to meteoritic values.

Solar history

Our knowledge of solar history is derived from:

  • meteorite geochemistry
  • geological proxy data
  • historical observations

Historical observations of solar behaviour, geomagnetism and other complementary sources are summarised in Solar History: An Introduction (Springer 2010).
