Scientists Discover Massive Network of Vanished Riverbeds on Mars

Scientists have discovered a massive network of vanished riverbeds on Mars. Researchers studied the sinuous ridges located in the southern highlands of Mars, in an area called Noachis Terra. They worked with data recorded by three modern orbital instruments. The team mapped the location and extent of the ridges. The result impressed the scientists: they discovered an incredibly long network of vanished riverbeds.
