Spacecraft spots the tallest mountain seen on Saturn's moon TitanMashable

Anyone up for a low-gravity hike on an icy moon?
The Cassini spacecraft, which has explored Saturn and its moons from close range for about 12 years, spotted a relatively high mountain peak on Titan, the ringed planet's largest moon.
The mountain is about 10,948 feet tall — slightly shorter than Oregon's Mount Hood — and was found in mountainous ridges called the Mithrim Montes, according to NASA.
"It's not only the highest point we've found so far on Titan, but we think it's the highest point we're likely to find," Stephen Wall, deputy lead of the Cassini radar team, said in a statement.
Titan is an incredibly hazy planet, with a thick atmosphere rich in nitrogen, so Cassini scientists used the spacecraft's radar instrument to peer through the haze and check out the surface of the world beneath.

Scientists have also found other mountains near the landing area where the Huygens probe touched down on Titan in 2005 after Cassini arrived in the planetary system.
Learning more about the moon's topography can help scientists piece together a geological history of the cold moon, which may harbor an ocean beneath its crust.

"But Titan's extremes also tell us important things about forces affecting its evolution."
Scientists think that it's possible Titan could have some tectonic activity that's changing the surface of the moon, possibly producing the mountains seen by Cassini.
Titan also has lakes and rivers of liquid hydrocarbons — organic molecules made of hydrogen and carbon — which could erode the landscape over time.

Mount Everest, for example, stretches to more than 29,000 feet, while Mars' Olympus Mons — which climbs up to an impressive 84,480 feet — is the largest volcano yet found in the solar system.
Mountains even appear in the most unlikely parts of our cosmic neighborhood.
Pluto, which was one thought to be an icy, cratered rock, actually has mountains made of water-ice the size of the Rockies and Appalachian mountain ranges on Earth.
