1. There are a lot of them (seven).
2. They are all Earth sized.
3. There are a lot of them in the habitable zone (three).
4. Even those not in the habitable zone could contain liquid water under certain circumstances.
5. This star is insanely close-by (39 ly).
Basically, if you're looking for a second Earth, this is an incredible gift. Even if we don't find a second Earth among these seven planets, they could tell us a lot about the likelihood of life around red dwarf stars, which is significant, because the vast majority of stars are red dwarfs. That's in addition to the information they can probably provide on planet formation and makeup.
