He look up at sky when he saw a star appear, increase in brightness. What could this be?
That description sounds like one may observed a transient astronomical event known as a nova. A nova occurs when a white dwarf star in a binary system accretes material from its companion star, causing a sudden thermonuclear explosion on the surface of white dwarf. This results in rapid increase in star's brightness, then may followed by a gradual fading over course of several days or weeks. Novae are distinct from supernovae, which are much more energetic events involving the complete destruction of a star. Without more details about the specific characteristics of what one can observed, it's difficult to say definitively.
