Pluto is still there, orbiting the sun in the Kuiper Belt. It's a dwarf planet, and while it's a fascinating object to study, it hasn't exploded or suffered any such catastrophic event.

It's possible you're thinking of something else. Perhaps you've seen a science fiction story or a news article about a fictional event. It's always good to double-check the source of information, especially if it sounds sensational or unbelievable!
