Scientists made a virtual supernova you can walk around

To build the 3D model, they looked at the elements inside a supernova (such as iron, silicon and argon) and the light they emit when heated. That gave them a way to figure out how fast the supernova’s debris are moving and in what direction. The result is a visualization showing the spherical component making up the outer parts of the remnant and the flat, disk-like component making up the inner
