What happened

A beautiful death: How a dying star created the Crystal Ball Nebula Lisa Lock Scientific Editor Andrew Zinin Lead Editor Planetary nebulae like the Crystal Ball Nebula (NGC 1514) are sort of like stellar obituaries.

Why it matters

Though crystal balls supposedly reveal the future, the Crystal Ball Nebula tells us more about the past.

Common ground

It shows us how a binary pair of stars met their end.
