the galilean moons of jupiter (via)
If you read Science Daily this is probably old news to you by now, but I was perusing the archives today and came across this fascinating article about Jupiter, and how it helped shape our entire galaxy. It's sort of like the ripple effect, except instead of throwing a pebble into a lake you're throwing a giant planet into a galaxy! By the way, I hope you don't mind my incredibly layman understanding of science. I know that my science posts would seem awfully pedestrian to anyone who actually knows their stuff, but I'm more fascinated and in awe of science than I am an expert at it, and I'll be the first to admit it ;)
