Ancient solar systems found around dead stars

Interesting find. I would think it unlikely these systems ever harboured intelligent life, as the Milky way is between 6-10 billion years old, and we took 4.5 billion to get this far, and our Sun has another 5 billion years to go, one would assume the stars were short lived and therefore likely did not have the chance to evolve to perhaps the level we have reached today. The mind boggles at what may have been lost though.

I call dibs on the Mining rights. Now to just invent a faster then light engine to get out there and start mining.

could these planets use to be gas giants?

Doubt they were gas planets, usually gas planets don't have much rock in the them.

Doubt they were gas planets, usually gas planets don't have much rock in the them. ive heard they got rocky cores, and ive also heard that once a star implodes, its gas atmosphere is stripped to the core.

Amazing news one more "steping stone" for the world knowledge the question is "what if human explore there to collect mines and build big star ships??" let it be not only a dream

Many of their progenitor normal stars may have been similar to our sun. If such a star was born ten billion years ago, and had a planet on which life arose, then after four to five billion years - six to five billion years ago - intelligent life may have evolved there and would have eventually moved into space.
