It's certainly a wonderful discovery! :-) But I wonder if this means that there's comething wrong with current theories on how solar systems form. How did 55 Cancri get two big gas giants close to its sun, and one further out, if the light elements in its protoplanetary disk fractionalized like ours did? Sol has the heavy stuff near the center and the lighter elements further out, but 55 Cancri seems to be all mixed up. Kevin Street
