Detailed explanation-1: -Seppo Mattila, Professor of Astronomy at the University of Turku, who also participated in the study, concluded: “By observing new types of supernovae, we gain valuable information about the later stages of life of massive stars. “This, on the other hand, creates new challenges for our theories on stars’ evolution.”

Detailed explanation-2: -Jan Brunowski, Johannes Kepler’s assistant, first observed the phenomenon in October 1604; Kepler studied it until early 1606, when the supernova was no longer visible to the unaided eye. At its greatest apparent magnitude (about -2.5), the exploding star was brighter than Jupiter.

Detailed explanation-3: -Through a phenomenon called gravitational lensing, three different moments in a far-off supernova explosion were captured in a single snapshot by NASA’s Hubble Space Telescope. The light from the supernova, which was located behind the galaxy cluster Abell 370, was multiply lensed by the cluster’s immense gravity.

Detailed explanation-4: -For the first time, astronomers have observed the final days and death throes of a red supergiant star before its final collapse and massive explosion into a supernova. Supernovas are usually only detected after they happen, although a few of a different type have been caught in the act of exploding.

Detailed explanation-5: -Supernovae – the Explosions of Stars The answer to this question will impact our understanding of how stars evolve, how they create and spread the elements that comprise the periodic table (and our bodies), and how we use them as tools for other experiments in astrophysics.
