Will UY Scuti end in Supernova?

UY Scuti is a red super-giant star  the constellation Scutum. It is one of the largest star by radius. UY Scuti is located a few degrees north of the A - type star  Gamma Scuti and northeast of the Eagle Nebula. 

UY Scuti is located a few degrees north of the A - type star  Gamma Scuti and northeast of the Eagle Nebula. Due to its distance and location in the Zone of avoidance within the Cygnus Rift, only it's 9th magnitude is visible. It is classified as a semi regular variable with an approximate pulsation period of 740 days. The star is over 1,000 times bigger than the our star and over 100,000 times more luminous than the Sun.It has a maximum brightness of magnitude 8.29 and a minimum of magnitude 10.56.
The star's mass is uncertain because it has no visible companion star by which its mass can be measured through gravitational interference (expected to be between 7 and 10 M☉). The luminosity is then calculated to be 340,000 solar luminosity at an effective temperature of 3,365 ± 134 K.

A supernova is a astronomical event which occurs during the last stages of a massive star. The original object, called the progenitor, either develops to a neutron star or black hole or it is completely destroyed. It fades after several weeks or months. The word supernova was coined by Walter Baade and Fritz Zwicky in 1929. The most recent directly observed  supernova in the Milky Way was Kepler's Supernova in 1604. 


UY  Scuti's Fate -


Based on current models of stellar evolution, UY Scuti has begun to fuse He , and continues to fuse H in a shell around the core. It's core is metal-rich.

After fusing heavy elements, its core will begin to produce iron, disrupting the balance of gravity and radiation in its core and leading to a core collapse supernova. UY Scuti would become a supernova but the star’s low mass indicates it would not be an outstanding explosion. It is not massive enough for UY Scuti’s remnant to be a black hole, a neutron star. It would have marginal impact on the Earth, a addition to the night sky, somewhat like Kepler's Supernova back in 1604.

Mahabharata - Indian biggest epic

Mahabharata, often referred originally as "Jai Samhita" is the greatest epic of all the time. The longest poem ever written, consists of over 1,00,000 couplets (2,00,000 verse lines) describes the solidity of it's content and gravity of knowledge people held in the golden, celebrated history of India. " Whatever is here may be found elsewhere, what is not, cannot be find anywhere else ."says one of the the most introducing verse of the Sanskrit epic. After going through the epic and with my little knowledge gathered, I can assure you that this epic is whole in itself as the verse above describes. Mahabharata is the cauldron of emotions, insecurities and jealousies. It overshadows each and every kind of emotion that we humans feel. Every kind of relationship through which humans can associate with each other is described here in some way or other. The Mahabharata is an intricately woven saga of hatred and love, bloodshed and noble thoughts, courage and cowardice,...

Mahabharata characters and conclusion

Krishna, is the mentor, the teacher, one who is everyone's friend and the most knowledgeable. He was the master of the power play , the brain behind the conclusion of the story. One of the most successful and calibrated life in whole of Indian mythology is of Krishna, considered as the 8th incarnation of Lord Vishnu. Draupadi, is my all time favorite lady of Indian mythology. She is one of the most controversial and misunderstood character because of her bold decisions and moves, which was centuries ahead of time. Her life is full of hardships, with endless sequences of suffering time to time. But she stood all alone, fought for her self- respect and sacrificed everything to counter the injustice done to her all her lifetime. She was married to five, mistreated in the gambling game by her own husbands, was attempted to disrobe in a hall full of men, was sent in exile of 13 years along with her husband, fought a war against her own family members and abusers, lost the lives of ...
