Snow Job

Scientists have observed the planetary accrection disc around a new star as it is condensing to form one of the planets that star will have one day. What they've seen this time is where the "snow line" around the star that marks interior rocky planets from outer ice giants is. The discovery helps confirm a number of guesses about planetary formation theory, and so is figuratively cool as well as literally so.
