A hundred million light-years from Earth, a rare supernova is bursting. The star, known as “Supernova LSQ14fmg” was identified by a 37-member international research team. The team was headed by Physics Assistant Professor Eric Hsiao of the Florida State University (FSU).

The Astrophysical Journal, published their research. This helped to discover the roots of the supernovae group to which the star belongs.

The features of this supernova is that it becomes progressively brighter. It is also one of the brightest explosions in its class making it completely unique. Eric Hsiao said, “This was a peculiar and odd case, and our reasoning for it is equally fascinating.”

Stars go through a kind of life cycle, and supernovae are low-mass stars’ exploding finale. They are so strong that they form the origin of galaxies; and so bright that even halfway through the observable universe we can detect them from Earth.

Type Ia supernovae were vital elements to explore what is considered as dark energy; which is the name given to the mysterious energy which causes the universe’s current accelerated expansion. Given their significance, astronomers knew nothing of the source of these supernova explosions; other than that they are the white dwarf star thermonuclear explosions.

The research says that such a supernova will become stronger as the nickel becomes more visible; then softer as the supernova cools and the cobalt and iron decay of the nickel.

The research team also noticed evidence of the development of carbon monoxide. These observations led to their inference on the way to being a planetary nebula, the supernova exploded within what had been an asymptotic giant branch (AGB) star.

Seeing how the observation of this interesting event agrees with the theory is very exciting,” said Jing Lu, an FSU doctoral candidate and a co-author of the paper.
