Kelika says:

""Originally believed to be a typical nova eruption, it was then realized to be something completely different. The reason for the outburst is still uncertain..."

This animation is a morph between a number of Hubble images, showing the light echoes expanding around the star (reflected from nebulas and other stellar material expelled earlier)"
