Orginal Title:Study of Equatorial Ridge on Iapetus Suggests Exogenic OriginYou Really Don't Prefer The Original Title, Do You? A combined team of researchers from Brown University in Rhode Island and the Lunar and Planetary Institute in Texas is suggesting in a paper they've uploaded to the preprint server arXiv, that an equatorial mountainous ridge on one of Saturn's moons has an exogenic origin.
