What Would Happen When A Massive Star Dies In A Strange Supernova Explosion?

Astronomers have discovered a strange supernova in a supposedly the largest star that exploded in a supernova. Named SN2016iet, and found in November 2016 by the European Space Agency (ESA) through the Gaia satellite, the three-year researched supernova has astonished the science team with its unconventional behavior.

The reason SN2016iet is considered surreal is that it emits much energy with a longer-lasting duration than any previous supernova observations. It was formed from a star with 200 times larger than the Sun’s mass. Also, it is located 54,000 light-years far from the middle of the dwarf galaxy.

This result has been in official publishment on the AstroPhysical Journal. Sebastian Gomez, the leader of the astronomer group, said the team observed unusual chemical reactions with much lower metal than previous supernovae observations. As reported by CNN, he even suspected the team's data set as compared to the unusual signals found. He added that unlike supernovae that could disappear when encountering the light from host galaxies within months, SN2016 has its own properties. The extraordinary brightness and self-isolation have made it possible for the team to further study the supernovae evolution in the future. As such, potential observations are about to be released with his expectations.

The special feature of SN2016iet is that it belongs to a gigantic old star, which normally tends to die, and yet ever occur in a chaotic universe. It is also the first-ever observed pair-instability supernova. Scientists believe that the reason for such mysterious phenomenon is the loss of 85% of the star's mass after millions of years, causing the collision of debris with the supernova. Consequently, a pair-instability supernova is formed after the core of a dying star generates gamma-ray radiation. This results in particle-antiparticle pairs that destroy the star with thermonuclear power.

This finding further clarifies the complexity of the cosmo and assisted astronomers in analyzing how the universe has been formed and developed.
