சனி கிரகத்தின் சந்திரனில் நதி கண்டுபிடிப்பு - நாஸா

NASA’s Cassini spacecraft has spotted a river system stretching more than 400 KM on Saturn’s moon Titan. Many lakes and small rivers have been found already on Titan but the newly discovered stream is the largest yet and represents the first time scientists have seen such a vast liquid system on any world other than Earth.Titan mini-Nile doesn’t flow with water, which freezes to be hard as stone on the moon, but rather liquid hydrocarbons such as methane and ethane. From its headwaters, the flow follows a fault line and runs into the Kraken Mare, one of three gigantic seas that cover Titan’s northern hemisphere. Titan’s liquid cycle also includes seasonal downpours, which have been spotted from orbit. Whether all this liquid improves the chances for life on Titan remains an open mystery.
