The twisty eruption of a dying star has finally been revealed in all its 3D glory.
A team of scientists led by a high school graduate has reconstructed the complicated and mysterious nebulae that make up one of the most famous stellar ghosts in the sky – the Cat's Eye Nebula.
The Cat's Eye Nebula, also known as NGC 6543, is what is known as a planetary nebula. They're not related to planets at all, however; the term came about because their round shape resembles planets. Such nebulae are what's left over after a star – like the Sun – runs out of fuel to burn and reaches the end of its life.
They can't be easily explained under the current model of planetary nebula formation, called the interacting stellar winds model. So, he did something about it. He enlisted the aid of astronomers Wolfgang Steffen of the National Autonomous University of Mexico and Nico Koning from the University of Calgary in Canada and employed the use of astrophysical modeling software SHAPE to deconstruct what is going on inside the central region of the Cat's Eye Nebula., supplied some of the data used.
