supernova

At that spot, they found the shining remains of a supernova.

They say that this White Dwarf wrapped itself in a blanket of stolen gas that caught alight quickly, sending a pulse of pressure into the core of the star that ignited the supernova.

Such simulations could shed light on major open questions in physics, including the imbalance of matter and antimatter, the creation of heavy elements inside supernovae, and the behavior of matter at ultra-high densities.

Scientists have long hoped to observe this initial moment because it helps answer key questions about how massive stars end their lives as supernovae.

This resolves a long-standing tension in cosmic ray research: while supernova remnants are known to produce cosmic rays, both data and theory suggest they cannot account for the energies seen at and above the "knee."
