No ocean, say scientists, but Titan's 'slushy tunnels' could still harbor life

Later, the Cassini-Huygens mission revealed what lay beneath - a distinctly alien world with oceans that might seem similar to our own, but which are made up of liquid hydrocarbons rather than water.

For a long time, scientists have speculated over whether oceans of liquid water might also exist on Titan, deep beneath its surface - a place where alien life forms may exist to this day.

Now, though, thanks to new research headed up by NASA/JPL planetary scientist Flavio Petricca, it has been determined that, rather than a subsurface ocean, Titan is actually more likely to be home to smaller pockets of subsurface liquid water.These 'slushy tunnels', however, could still potentially offer a place for life to thrive.

"We're not certain if having widespread liquid pockets instead of a global ocean makes Titan more or less habitable," said Petricca. "It will be interesting to find out."

Fortunately, NASA's upcoming Dragonfly mission will seek to answer questions like this.

Consisting of a robotic, airborne probe capable of landing at and taking off from various sites, it will delve into the mysteries of Titan like never before.

Dragonfly is currently scheduled to launch in 2028 and will arrive at Titan in 2034.
