No they have not. I also saw news reports that misrepresented the actual scientific findings.
Huge progress has been made in determining planets that lie in the "habitable zone" of other star systems, and even inferring a bit about their overall chemical composition. That's not nearly enough to guess at whether they can support human life.
But here's the latest research, which is really mind boggling. They've got frikking thousands of candidate planets....
https://en.wikipedia.org/wiki/List_of_potentially_habitable_exoplanetsI was actually talking about that potentials. If you do talk about potentials then that does mean as well right that those planets were listed really are capable of supporting human lives and of course the only thing we could actually do that is by progressing the research within the potential planets. I have seen another article about a new discovered planet that happens to have a little bit of similarity within the earths surface.
