Cassiopeia A Supernova Resembles Swiss Cheese: Here's Why



Supernovae are known to be large explosions that occur at the end of the life cycle of a star but much about how they happen remains a mystery. Findings of a new study published in the journal Science on Jan. 30, however, could partly shed light on this mystery.

Study researchers Dan Milisavljevic, from the Harvard-Smithsonian Center for Astrophysics, and Robert Fesen, from the Department of Physics and Astronomy at the Dartmouth College, studied the supernova remnant Cassiopeia A in a way that allowed them to come up with its three dimensional model that revealed large scale structures in the interior. The researchers described the interior of Cassiopeia A as something that resembles a swiss cheese
