Now, astronomers have a new tool to better understand the asymmetrical shapes of supernova explosions, and thus how stars explode in the first place. An instrument called “WIRC+Pol,” located at Caltech’s 200-inch Hale Telescope at Palomar Observatory, has delivered its first science results, which show that a supernova called SN 2018hna exploded in a shape more like an ellipse than a sphere, similar to the well-studied supernova remnant called SN 1987A. ....
