What moves rocks on Mars
''Wind storms and dust devils rage across Mars, so it's logical to suspect they blew the rocks. But the Red Planet's atmosphere is so thin that winds would have to be "10 times Hurricane Katrina" to pick up the stones, Pelletier told New Scientist. And wind-blown rocks would have no reason to stop where they were nearly equidistant from their neighbours.'' [source]
Jupiter-Sized Planets Grow Up Fast
''Compared to small, rocky worlds like Earth, Jupiter-class gas giant planets form quickly or not at all, a new study shows.'' [source]
