**"Stars are spherical balls of gas, and so you might think that when they end their lives and explode, that explosion would look like a uniform ball expanding out with great power," said Fiona Harrison, the principal investigator of NuSTAR at the California Institute of Technology (Caltech) in Pasadena. "Our new results show how the explosion's heart, or engine, is distorted, possibly because the inner regions literally slosh around before detonating."** http://www.nasa.gov/jpl/nustar/supernova-explosion-20140219/#.UwUUA6ZFu0E What made the inner regions of a collapsing star to slosh? Is the core which is supposed to be impervious and resistive to deformation due to degeneracy pressure would slosh too? Perhaps it will, considering that it generates shock waves that ultimately rips the star apart.
