While exploding, supernovas not spherical
X-rays reveal uneven allotment of element made by blowup

Giant stars are slightly off-kilter as they go kablooey, research in the Feb. 20 Nature suggests.
When massive stars run out of elements to fuse in their core, they collapse under their own gravity; the imploding material then bounces off the core and explodes in a bright display known as a core-collapse supernova. But computer simulations indicate that if material collapses symmetrically, as scientists long assumed, a star would not explode.
To address this conundrum, a team including Caltech ...
