Scientists studying Titan, Saturn's moon, have discovered a strange and frozen element that stretches for some 6,300 kilometers (3,300 miles) across its tropical region and could indicate the existence of a ice volcano ".
The planet scientist Caitlin Griffith of the University of Arizona led a team that studied the odd formation based on spectral images taken by the Cassini probe, using an infrared spectrometer to pierce the beam. dense atmosphere based on nitrogen.
"This frozen corridor is confusing because it does not correspond to any surface features or measurements of the subsoil", Griffith speaks of the long, almost linear corridor that spans 6,300 km through the moon.
Their discoveries indicate "The water ice is exposed unevenly, but not randomly, on the tropical surface of Titan", she added.
Scientists expected the moon's surface to be covered with organic sediments that rain when the sun breaks methane molecules into the atmosphere, as described by Griffith "Disturbed version" from Earth, but were surprised to find an icy tendril gripping the space rock around his waist.

A "crazy, methane-based" extraterrestrial life could exist on the surface of Titan.
The team believes that this may be a remnant of a bygone era on the satellite.
"It is possible that we see something that remains a remnant of a time when Titan was very different", Griffith told New Scientist. "It can not be explained by what we see there now."
The most likely theory is that it is the remnant of a massive, ancient "ice volcano" that produced water, ammonia, or methane instead of the magma that we had. habit of seeing on Earth.
