The science sections of various newspapers shall report this news.
AND I am glad that we can spotted yet another planet similar with earth, not because we can moving once the earth had been thoroughly exploited and polluted, it’s just showing it’s not feasible at all to move to another planet. The distance is 20 light years.
It’s unlikely human race will able to creata machine capable of speed achieving light-years (unless it’s in a movie)
So, take care our planet earth and riding on whale’s back is not cool.
