After creating a new 3D model of the final moment before a star explodes, researchers have come to know that the end of star is not a 'calm before the storm' moment, but a chaotic and messy one. It was found by the researchers that material is continuously ejected by the star before the big explosion occurs.

The study - conducted by W. David Arnett, Casey Meakin and Nathan Smith from the University of Arizona and Maxime Viallet from the Max-Planck Institute for Astrophysics - provided a new insight into the death throes of supernovae.

The model is the first to show how a supernova begins to collapse in 3D. The researchers noticed that turbulent mixing of elements inside the dying stars forces them to expand, contract and spit out matter before it finally explodes.

It has been showed by the new model that a star with a turbulent interior throws out star remnants before the final explosion occurs. So, it could be said that the end moment of a star is similar to heating a pot that causes water to boil over the edge.

"We still have the concentric circles, with the heaviest elements in the middle and the lightest elements on top, but it is if someone put a paddle in there and mixed it around", said Arnett, who described the model in the journal AIP Advances.

He added that as the explosion time comes near, the materials begin to mix together so as to lead the star to flop around and eject material until explosion happens.

The astrophysicist's 3D model was created after getting better data and faster computers than previous models. The supercomputers Arnett used in the 1970s would have taken 40 years to run these models. He said that there is a need for more data because supernovae are extremely rare and difficult to find.
