From Earth the Sun is obviously the brightest star.
Otherwise Sirius (The Dog Star) is brightest star discovered so far with a magnitude of -1.42.
One of the most luminous stars in the Galaxy is called The Pistol Star (but dust hides it from view)
Yes, from Earth the Sun is the brightest star. But that's not the question: the brightest star in the universe is certainly not the Sun, nor is it Sirius; Spica for instance, is over 10 times the mass of the Sun, thus having a far greater luminosity.
But the light years separating Spica from Earth reduces it to the 15th brightest star in the nighttime sky. And the Pistol Star is only one of the brightest stars in the Milky Way Galaxy... The universe however, houses many stars superior to the Pistol Star.
The problem with the question is it refers to such an astronomical entity, the vast universe. And as such, it may never be able to be answered with complete accuracy...
That isn't the question either, the brightest star known in the universe is R136a1, a blue hyper-giant which is not only the most massive star known, at 265 solar masses, but the brightest.
It shines at 8,700,000 times the luminosity of the sun and is a member of the R136, a super star cluster around the centre of the tarantula nebula in the the magellanic cloud, a satellite galaxy of the Milky way.
the largest known star in the universe is vy canis majoris, but there may be bigger ones out there.
the most massive (in weight) star known is R136a1, a blue hypergiant star at an estimated 265 solar masses, also holding the record as the most luminous, shining at 8,700,000 times the luminosity of the sun. A member of the R136 super star cluster around the centre of the tarantula nebula, in the large magellanic cloud, a satellite galaxy of the milky way.
The largest star is VY Canis Majoris, is 4900 light years away and its in constellation Canis Major, which it resides and which is a red hypergiant, is 1800-2100 larger than our sun
Fact:If it was replaced by sun or replaced in the center, it will shallow all planets but Uranus and Neptune.
the vy canis majoris is the largest known star
The largest known star in our solar system is the red hypergiant VY Canis Majoris. It is also known as VY CMa. It is happens to be the brightest of its type.
As of November 2014, the largest star we know of is UY Scuti.
VY Canis Majoris is the name of the largest star that we know of in our universe.
Generally the largest star we know about is VY Canis Majoris a hypergiant of about 2,100 times the radius of our Sun. However, in the Universe, we cannot be sure. We know that there should have been population III stars that would have been bigger but these have not yet been sighted. Even if they were, they would have died billions of years ago.
Beacause it is the biggest star in our universe
We haven't observed all of the stars in the Universe, so we don't know what is the largest yet.
Trifid is a nebula, not a star. For a the largest star, see related question.

We will never know the largest star in the Universe. The biggest star in our Galaxy is VY Canis Majoris.

"THE UNIVERSE" It's self, is classed as a structure so The Universe is the largest structure that we know of.If you mean: 'single' object it would be a star called: VY Canis Majoris.If you mean: largest collection of stars and such as a galaxy, it would be: IC1011.If you mean: a cluster of Galaxies it would be: the Sculptor Supercluster.
