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.
