      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.

          Time Domain Astronomy is astronomy in four dimensions and its allowing us to unpick the largest and quickest celestial events in never before considered ways: http://www.gresham.ac.uk/lectures-and-events/the-transient-universe Many disparate phenomena in both the local and the distant Universe have properties which are time-variable, and constant monitoring of the sky at all wavelengths is required to catch the occurrence of these events. Observations of the transient Universe cover all of modern astrophysics – from variable stars to unusual and violent events such as gamma-ray bursts.
