Our sun is not the brightest star in the universe. It only appears brighter because it is much close than any other star. The brightest star as it appears in the sky is Sirius.
Brightness is related to luminousity and distance. On Earth, the brightest thing would be a nuclear explosion. In space, the brightest thing would be a supernova, but it all depends on the distance from it.
the biggest and brightest star, being a red supergiant, is VY canis majoris, the sun is invisible in scale to this colossus. so the biggest and brightest types of stars are red supergiants.
Yes. It's normally one of the brightest objects in the sky.Easily. It's one of the brightest objects in the night sky. If you can see the star Sirius, anything noticeably brighter than that and not reddish in color is either Jupiter or Venus (or the Moon, but that one's kind of obvious).
Ganymede is the largest moon of Jupiter and would appear the brightest from the planet due to its size and reflectivity. Ganymede's icy surface reflects a high amount of sunlight, making it one of the brightest objects in Jupiter's sky.
The brightest objects are hypernovae and the darkest objects are black holes.

Generally the brightest objects seen in the sky are the moon, some planets, (notably Venus and Jupiter) and stars, Sirius being the brightest.
Our sun is not the brightest star in the universe. It only appears brighter because it is much close than any other star. The brightest star as it appears in the sky is Sirius.
They are called quasars. We occasionally observe short bursts of gamma radiation which outshine even quasars temporarily, but astronomers aren't absolutely certain yet what causes them.
Yes, quasars are extremely luminous astronomical objects found in the distant universe. They are powered by supermassive black holes at the centers of galaxies, making them some of the brightest and most energetic sources in the cosmos.
Alpha centuri is one of the brightest stars in the universe.

Hypernovae are the brightest object in space while black holes are the darkest object in space.
A black hole. Nothing gets out of it; but because of interactions with the matter around it, black holes can still be the brightest objects in the Universe! Do some reading on quasars, for more details.

As the question specifies brightness, the brightest star in the Universe is our Sun - because it is the closest star to us. The most luminous star is another question: See related question.
