Hubble sees light echoes of supernova blast in apart galaxy
The Hubble Space Telescope prisoner a light echoes of a apart supernova resilient off a dirt cloud in a apart galaxy.
On Jan. 21, 2014, a star in a M82 galaxy, that lies 11.4 million light-years divided and can be found circuitously a hoop of a Big Dipper, exploded in a shining supernova named SN 2014J.

Over several months from 2014-2017, Hubble incited a camera towards M82 to constraint a outcome of a large blast, witnessing light bouncing off a hulk dirt cloud that stretches 300 to 1,600 light years from a supernova itself.Â
Like a sputter in a pond, a relate outcome occurs as light from a blast bounces off a circuitously dirt cloud and travels during opposite distances to strech Earth.Â
SN 2014J is a Type Ia supernova, where dual tiny stars share an orbit called a binary star system. One tiny star in a complement is a white dwarf, that starts to collect element from a messenger star. After it collects too most mass, a white dwarf explodes in a supernova.
This is a closest form of blast in about 40 years.
