Some huge, some small. Some zip, some crawl. The cosmos is full of objects that defy expectations....
The biggest: UY Scuti
Just like in the DC Universe, sometimes the clearest way for astronomers to express something is truly extraordinary is to add the prefix super. Its the case with Superman, as well as with supergiant stars a fitting category for the largest known star in the universe, UY Scuti.
One day, the Sun will become a red giant. But if it had started its life with a dozen or so times its current mass, it could have eventually evolved into a red supergiant. (UY Scuti has already shed a lot of mass.) The biggest of these stars, sometimes called hypergiants, can swell to more than 1,000 times the size of the Sun. But UY Scuti, located near the center of the Milky Way in the constellation Scutum, is around 1,700 times the Suns width.
SNIP
But like any red supergiant including Betelgeuse UY Scuti is destined to end its life with a bang. After exhausting the helium fuel in its core, it will ferociously forge increasingly heavy elements. And as long as UY Scuti doesnt expel too much mass over the course of its remaining life, it will eventually start producing iron.
Making iron is a death sentence for stars. Unlike when it combines lighter elements, when a star forces two iron nuclei together, it doesnt release any energy; it instead takes energy away from the environment. This causes a runaway collapse where the star no longer generates enough outward pressure to keep it from imploding under its own gravity.
The end result? A powerful core-collapse (type II) supernova that will finally albeit briefly make UY Scuti visible to the naked eye from Earth.

That might mean that solar flares in the Scrotum system are simply cases of premature ejection...
It would cover out at least to Jupiter. Let me get my tape measure.
Bada-boom, bada-bing, tssssssshhh (cymbal roll). :-)
Many do and did believe in God. This includes many famous and not so famous astronomers. So what specifically is your point?
And in its sky was such a sun as no opium eater could ever have imagined in his wildest dreams. Too hot to be white, it was a searing ghost at the frontiers of the ultraviolet, burning its planets with radiations which would be instantly lethal to all earthly forms of life. For millions of kilometers around extended great veils of gas and dust, fluorescing in countless colors as the blasts of ultraviolet tore through them. It was a star against which Earths pale sun would have been as feeble as a glowworm at noon.― Arthur C. Clarke, Childhood's End
I'm gonna need at least a week's notice on this. Okay?
Ya mean possibility? Btw, you don't make the rules regarding what people should believe and or how many should believe or accept whatever you believe. It doesn't work that way.
Deneb in the Constellation Cygnus is a true giant.
You have 2-3 Billion years to prepare.................
Thanks MtnClimber, I like how you work. :^)
Thank you. I have added that to my long range calendar.
Nearly out to Uranus!
