Expanding light echo spotted around supernova
Hubble images reveal an expanding shell of light from a supernova explosion sweeping through interstellar space three years after the stellar blast was discovered. The "echoing" light looks like a ripple expanding on a pond. The supernova, called SN 2014J, was discovered on Jan. 21, 2014.
