An ancient solar storm helps pinpoint when Vikings lived in the Americas, and using magnets to deftly move non-magnetic metals. ﻿In this episode:00:53 Pinpointing Viking presence in North AmericaIt’s well-understood that Vikings went to North America around a thousand years ago. However, working out a precise date has proven difficult. Now, thanks to an ancient solar storm, researchers have been able to identify an individual year when Vikings were definitely living on the continent.
