    Yes, they exist. They are extremely hot compared to our sun.

    Indeed.  Blue stars are huge, hot, massive stars - many times larger than our sun.  They burn through their fuel much more rapidly than our sun does, and - when they begin to produce iron in their cores, that means the end of their life is approaching.  Unlike our sun, which will expand into a red giant, then finish off it's existence as a white dwarf, Blue Stars suddenly collapse, then explode in a supernova explosion, often as bright as a whole galaxy.

    Yes, but they're not bright blue. They're blue-tinged white stars.

    Yes, they sure are real.  The hotter the star the more blue you will see.
