Which star is the brightest? Much brighter than the Sun? Are all Stars nuclear fusion like the Sun? During nuclear fusion, does the process create electron? Because more neutrons are formed to create Helium from hydrogen.
Apparent brightness from Earth is the star Sirius in Canis Major Yes all stars get there energy from fusion. Stars depending on their mass, undergo fusion right up to Iron/Nickel. If you cut a large star in half through the poles, you would find layers and layers of various elements. Is this a genuine science question or do you have an agenda?
There are many many stars bigger and brighter then the Sun which is classed as a yellow dwarf star. G2V classification
Yes it was the "Bethlehem" star. When it lined up with the "Three Kings" stars in Orion it pointed to where the Sun rose on 24 th December which I think was when the Sun was placed on the cross , our Southern Cross. ...Sirius played an important role in Egypt as when it was observed to rise in the morning the priests could tell that the floods came two weeks later...neat eh.

The most luminous star I have been able to find a listing for is RB6a1 in the Large Magellanic Cloud. With an absolute magnitude of -12.56, it is 8,710,000 times more luminous than the Sun. It is over 160,000 light years away. If it where 10 parsecs (32.6 light years) away, it's brightness would appear to be somewhere between the total light of a full Moon and Betelgeuse going supernova.
