NASAs Hubble space telescope captures supernovas light echo

Over a period of two-and-a-half years, NASAs Hubble Space Telescope observed the light echo of supernova SN 2014J in galaxy M82, located 11.4 million light-years away. The echo happens when light from the explosion bounces off a cloud of a giant cloud of gas and dust near the supernova.
