Description
Despite the long held assumption that PWNe at high energy could be counted as "stable candles", detection of gamma-ray flares in the Crab nebula, led us to revisit our ideas about the working of such systems. Given the lack of resolution of current gamma-ray observations, analysis of variability was performed at other wavelengths in search for possible counterparts that could guide us to the origin of these violent events without much luck. I will review here the status of our knowledge of high-energy variability (and variability in general) in PWNe, as well as the various models that have been proposed, and what are the prospect of observing similar events in other systems.
