Decoding rare illuminating Superluminous Supernova

In a step towards probing the mysteries of the early universe, the Indian researchers have spotted an extremely luminous, powerful, hydrogen deficient, fast-evolving supernova that shines with the energy borrowed from an exotic type of neutron star with an ultra-powerful magnetic field. Supernovae (SNe) are extremely bright, super-powerful explosions of dead stars in the universe and the Superluminous Supernovae (SLSNe) among them are exceptionally rare.

Superluminous Supernovae (SLSNe) Explained:

Since their discovery, Superluminous Supernovae have baffled astronomers because they originated from very massive stars whose minimum mass limit is more than 25 times that of the Sun. It is worth noting that the distribution of such massive stars in our galaxy or in nearby galaxies is sparse in quantity. Among them, spectroscopically confirmed Superluminous Supernovae have been counted to about 150 entities. These brilliant blasts of dead stars are at least 10 times more powerful than any regular supernovae. They are the ancient objects that are among the least understood Supernovae because their underlying sources are unclear, and their extremely high peak luminosity is unexplained.
