Comet Lovejoy's wiggle offers glimpse of Sun's variable coronal magnetism (w/ video)

A team of researchers studying comet Lovejoy has discovered that as the ball of ice passed through the sun's corona in December 2011, its tail wiggled in a way that allowed them to better understand coronal magnetism.

In their paper published in the journal Science, the team says observations of Lovejoy's close call with the sun have helped them improve models used to describe the irregular nature of coronal magnetism.
