What types of stars do we need to watch out for if we want to see the development of a supernova explosion from the beginning?

A Supernova explosion is a rare event that can only happen to a massive star at the end of its “life” as a normal star. Therefore, it will take a very, very long time to monitor specific stars in anticipation of their explosion, and if such a task is posed, then only for supermassive stars with masses of up to 100 solar masses and higher, since the lifespan of these stars is the shortest.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
