The cnter of our MW glaxy is bustling with young & old stars,smaller blck holes & other varieties of stellar corpses all swarming around a supermassive blck hole called Sagittarius A*[A black hole is a region of spacetime where gravity is so strng that nothing can escape from it]
Now,Coming to STARS,
Stars are clumps of dust & hot burning gases in a nebula(starwomb)whch come together due to gravity.These stars,due to nuclear reaction of gases in the core of the star,emit light of their own tht provides enough enrgy to make them shine brightly for many yrs
