I came across this article about how Jupiter has been flinging comets toward earth. For the longest time, scientists have thought Jupiter has acted as a shield, protecting our planet, but now it looks like that’s not the case. The answer is rather complex. Namely, that in some cases Jupiter does protect earth, but in other cases it flings comets that would otherwise be no threat to us our direction. Apparently, Jupiter has a habit of capturing comets, letting them hang around for a little while, and then spitting them back out into space. Pretty wild!
