Astronomers have discovered a powerful ultraviolet laser beam, several times brighter than our Sun, shooting towards Earth from Eta Carinae, one of the most unstable stars in the Milky Way.

There are many stars that are brighter than the sun. Deneb shines the brightest in the constellation Cygnus and is much farther from Earth than most of the other stars you see. Deneb is about 100,000 times brighter than the Sun. HR 5171, has a diameter 1,300 times the sun and is a million times brighter than the sun. R136a1 weighs up to 300 times the mass of the Sun and is close to 10 million times brighter than the sun.
The sun appears brighter than Sirius does because it is about half a million times closer to us.
super-giant star
Green laser sight is used for accuracy in hand guns and rifles. The usefulness of green laser sight is reported to be fifty times brighter than the human eye and more accurate than red laser.
Well, Light Amplification by Simulated Emission of Radiation (LASER), which is artificially made, is like a million times brighter that sunlight. And that's all I know. Find out more in Wikipedia yourself. (P.S. No offense for that sentence.)
2 magnitudes brighter means it's about 2.512 x 2.512 times brighter. So that's about 6.31 times brighter.
Quite a bit more than that. A typical quasar is several times brighter than an entire galaxy that has no quasar.Quite a bit more than that.

It is four times as brighter. It is four times as brighter.
It is R136a1 and has an absolute magnitude 10 million times brighter than our sun
it isn't the sun is 450000 times brighter than the moon! no..
