The problem, the scientists report Monday in Nature , is that while the tiny galaxy dates from just 700 million years or so after the big bang, it's far more dusty than something this young and small has any right to be.
The dusty galaxy is just one of the recent surprises astronomers have found. "Last week," says Marrone, "we learned of an incredibly massive black hole in the early universe. Now we have this average galaxy with significant amounts of dust. We've had this cartoon picture of the early universe, but it's clear that we really don't know what's going on."
