If you are lucky enough to see a display of the Northern Lights in a clear dark sky, it's an experience never to be forgotten. Sometimes seen as wide ribbons or billowing curtains stretching across the sky, or sparkling and flashing swirls above your head, this is a phenomenon that has entranced and fascinated observers for thousands of years.
In this highly illustrated talk Dr Carolin Crawford (Camb) will discuss the how, where and why of the aurora, and the variety of shapes and structures they can form. She'll explain how their occurrence is intimately related to the Sun's activity and the Earth's magnetic field - leading to the charged particles of the Solar wind exciting atoms and molecules in our atmosphere to release light as these stunning displays. This talk is organised by Hurtigruten who will be arranging the alumni tour to Norway with Dr Crawford.
This event will be recorded and will be available to view on our website after the event.
