Without our Sun, there would be no heat, no light and no life on Earth. An eleven-year cycle of magnetic activity modulates its appearance, and the occurrence of eruptive events such as flares and coronal mass ejections. I shall discuss how these, in turn, affect the Earth - and how the Sun currently does not seem to be behaving as expected.

Gresham College has been giving free public lectures since 1597. This tradition continues today with all of our five or so public lectures a week being made available for free download from our website. There are currently over 1,700 lectures free to access or download from the website.
Professor Carolin Crawford
Outreach Officer at the Instituteof Astronomy and Fellow of Emmanuel College, University of Cambridge, Professor Carolin Crawford is one of Britain's foremost science communicators.
After receiving her PhD from NewnhamCollege, Cambridge, Professor Crawford went on to a series of fellowships from BalliolCollege, Oxford, Trinity Hall, Cambridge and the Royal Society. In 2004 she was appointed as a Fellow and College Lecturer at EmmanuelCollege, Cambridge, where she is now also the undergraduate Admissions Tutor for the Physical Sciences. Since 2005 she has combined her college role with that of Outreach Officer at the Institute of Astronomy at the University of Cambridge.
Professor Crawford’s primary research interests are in combining X-ray, optical and near-infrared observations to study the physical processes occurring around massive galaxies at the core of clusters of galaxies. In particular, she observes the complex interplay between the hot intra-cluster medium, filaments of warm ionized gas, cold molecular clouds, star formation and the radio plasma flowing out from the central supermassive black hole.
In 2009 Professor Crawford’s outstanding abilities at science communication were recognized by a Women of Outstanding AchievementAward by the UK Resource Centre for Women in Science, Engineering and Technology, presented for “communication of science with a contribution to society.”
Appointed as the 36thGresham Professor of Astronomy in 2011, Professor Crawford looks forward to presenting her Gresham lectures wherein she plans “to showcase the very latest developments and ideas in astronomy and cosmology, whilst putting them into the context of the process of scientific discovery.”
