Scientists have detected a remnant from a planet, whose star died, orbiting around the corpse of the star. Usually, when stars die in a supernova explosion, the resulting impact would obliterate everything around it. The interesting thing about this white dwarf is that a dusty ring has formed around it.
When the sun eventually dies out, it is thought that Earth will be like the dead planet that the scientists observed. Although we are far from that point, it might be best to start looking for ways to get away from it. Like going to Mars perhaps?

The Sun is too small to go supernova; what is expected to happen is that it will become a Red Giant star, and it may engulf the Earth, but this will probably not happen for another 5 billion years. See https://earthsky.org/space/what-will-happen-when-our-sun-dies for a better explanation.
