 Confirmation by other teams through additional high @-@ precision RVs would be most welcome . But if GJ 581g is confirmed by further RV scrutiny , the mere fact that a habitable planet has been detected this soon , around such a nearby star , suggests that η ⊕ could well be on the order of a few tens of percent , and thus that either we have just been incredibly lucky in this early detection , or we are truly on the threshold of a second Age of Discovery .
