Known Universe

Синопсис

Our Sun is a tremendous source of energy and danger for our planet, but it has nothing on the stars that lie beyond our own tiny solar system. The biggest star known to man is a hyper red giant…yet size doesn't always equal power when we see how smaller, blue super-giants burn many times hotter. We'll explore how a star becomes even more powerful in its violent supernova death, and how the most intense place in the universe may not be a star at all…but a black hole.
