UY Scuti resides more than 5,100 light years away from Earth in the constellation of Scutum near the center of the Milky Way, and it's currently classified as a red hypergiant variable star. Based on its sheer size, astronomers believe that it's no longer in its main sequence, and that it's on the verge of dying.18-Nov-2019
How long does UY Scuti have left?
Stellar evolution models tell that UY Scuti has already left the main sequence and has started fusing helium in its core. This means it is left with just 10% of its life. Stars like these have a short lifespan of a few million years compared to trillions of years for red dwarfs.
What happens if UY Scuti dies?
When it does die, it's expected to explode with the force of more than 100 supernovas. A supernova is the explosion of a star, and it's the largest explosion that takes place in space. So the force of 100 stars exploding would obliterate everything nearby.
Will UY Scuti become a black hole?
Long before UY Scuti goes supernova, Betelgeuse will have gone supernova and its a smaller star. UY Scuti will either become a Neutron Star or a black hole but a Neutron Star is the more likely of the two.
Can UY Scuti be seen from Earth?
UY Scuti is located in or galaxy the Milky Way, at about 5.219 light-years away from Earth. UY Scuti changes its brightness but it can be viewed from Earth as it is a pulsating star. It has an absolute magnitude of -6.2, UY Scuti is thus 340.000 times more luminous than our Sun.
Is UY Scuti hotter than the sun?
UY Scuti is releasing much more heat energy than the sun, but its surface is cooler. It's kind of like the difference between a candle an an electric blanket.
Will UY Scuti go supernova?
UY Scuti will definitely explode as a supernova one day, but by the standards of supernovas it will be an “ordinary” one. That's because the power of a supernova depends on its mass, not size. And UY Scuti, at some 7–10 solar masses, is about average among “stars which go boom”.
What if Betelgeuse exploded?
If we were too close to Betelgeuse when it explodes, our atmosphere and cells would be fried by the radiation and gamma waves. When you're exposed to high doses of radiation, it can burn and scar your skin, cause genetic mutations, and can ultimately be lethal. Gamma radiation, in particular, is incredibly powerful.

How old is the UY Scuti?
Nomenclature and history UY Scuti was first catalogued in 1860 by German astronomers at the Bonn Observatory, who were completing a survey of stars for the Bonner Durchmusterung Stellar Catalogue. It was designated BD-12°5055, the 5,055th star between 12°S and 13°S counting from 0h right ascension.
