New Fenomena Of Supernova: It's Bright Again

Researchers recently have witnessed the phenomenon of light from a new supernova remnant. This incident rarely happens. The great thing of this phenomenon is the transition from a supernova event becomes a supernova remnant.

Supernovae occur when a star loses its nuclear energy, due to most sources of energy has been transformed into heavier elements. In certain circumstances between thermal energy, gravitational energy, the star was no longer able to maintain itself. So that the star exploded. The star that exploded was subdivided into two types, namely the bursting entirely (high energy: supernovae) or burst gradually (low energy: nova).

While the observed supernova is derived from an exploding star in Large Magellanic Cloud galaxy, and the radiation reaches the earth in February 1987. Supernova SN 1987A was later named. What is interesting is the supernova debris (debris remaining exploding stars) that has faded, now bright again. This means, there are other resources that are now emit light debris.
