Stars are a ubiquitous feature of our local Galactic environment. They do not last forever – but form, develop and evolve over timescales of millions or billions of years, eventually to expire in dramatic style. We look at the lifecycles of different kinds of stars, and in particular, what they reveal about our own origins.
Outreach Officer at the Institute of Astronomy and Fellow of Emmanuel College, University of Cambridge, and Emeritus Gresham Professor of Astronomy, Carolin Crawford is one of Britain's foremost science communicators.
After receiving her PhD from Newnham College, Cambridge, Professor Crawford went on to a series of fellowships from Balliol College, Oxford, Trinity Hall, Cambridge and the Royal Society. In 2004 she was appointed as a Fellow and College Lecturer at Emmanuel College, 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 Achievement Award 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 36th Gresham Professor of Astronomy in 2011, Professor Crawford delivered a series of free public lectures where she carried out her intention “to showcase the very latest developments and ideas in astronomy and cosmology, whilst putting them into the context of the process of scientific discovery.”
