We found evidence that a massive star exploded in a lopsided fashion, sending ejected material flying in one direction and the core of the star in the other. The findings offer the best proof yet that star explosions of this type, called Type II or core-collapse supernovae, are inherently asymmetrical, a phenomenon that had been difficult to prove before now.

The still unraveling remains of supernova 1987A are shown here in this image taken by our Hubble Space Telescope. The bright ring consists of material ejected from the dying star before it detonated. The ring is being lit up by the explosion's shock wave.
