If some stars that are lightyears away are dead, does that mean the exoplanets we find are also dead?

Question

I get really excited over exoplanets that are Earth-like so I’m wondering how this works.

Answer 1

All undisputed exoplanet discoveries are in our own galaxy, most of them within a few thousand light years, and most of them around stars that are somewhere in the middle of their multi-billion-year life. We have found ~5000 exoplanets so far. It’s likely all of them still exist with essentially unchanged stars.
