While it's true that stars eventually die and can undergo various transformations like novae or supernovae, it's not possible for an individual to witness a star exploding in real time. Stars are incredibly distant, and even the closest ones are many light-years away. Light travels at a finite speed, meaning that the light we see from distant stars left them many years or even centuries ago. Therefore, it's not possible to witness a star exploding in the night sky anytime soon.
