Researchers are solving the mystery of a supernova that occurred earlier this year in a galaxy 11 million light years away.

They believe that this phenomena is extremely important to study because they provide information about the universe, galaxy expansion and galaxy evolutions.

The supernova was named 2014J, a Type Ia supernova that occurred when there was an explosion of a dwarf star.

According to researchers, the star's inner core ran out of nuclear fuel and ejected its outer layers causing the explosion.

Its mass increased about 1.4 times the size of the sun until its extreme temperature caused the carbon of the star to undergo nuclear fusion.

The nuclear fusion then spread rapidly throughout the star resulting in a thermonuclear explosion that ripped the star.

Miguel Perez-Torres from the Spanish National Research Council said that supernovas play a fundamental role in the chemistry of galaxies and their evolution.

He said that supernovas are responsible for creating heavy elements including elements that cannot be formed in the interior of normal stars.

Torres also explained that despite the fact that a Nobel Prize was awarded in 2011 for the use of Type Ia Supernova to discover the acceleration of the expansion of the universe.

Scientists remain baffled on the cause of this Type Ia supernova, he added.

Rob Besswick, one of the researchers, said that the supernova explosion that happened in the nearby Universe is a rare event.

The 2014J Supernova is the closest Type Ia supernova to be seen from Earth since 1986, he explained.

The chance of scientists seeing a supernova this close would not probably occur again until after another hundred years, he added.
