There may be far more water on the Moon than previously thought

There may be far more water on the Moon than previously thought When NASA and other space agencies from around the world eventually send humans back to the Moon in the coming decades they'll likely be doing so with a goal of eventually establishing scientific settlements in the not-so-distant future. 

Titan , Saturn ' s largest moon, might have a more violent past than astronomers realized. "This is a completely different explanation for the steep rims around those small lakes , which has been a tremendous puzzle," Linda Spilker, a Cassini scientist unaffiliated with the new study, said in a press

Many of the methane-filled lakes on Titan were likely formed after explosions of warming nitrogen left dozens of empty craters dotting the surface of Saturn ' s largest moon. "This is a completely different explanation for the steep rims around those small lakes , which has been a tremendous puzzle," said

Explosions may be responsible for the bizarre lakes on Saturn’s Titan © Provided by Penske Media Corporation saturn-titan Scientists have learned a lot about Saturn’s moon Titan thanks to NASA’s Cassini spacecraft, which orbited the planet for well over a decade before NASA, and the ESA had to pull the plug in 2017. The mission was a massive success, and it’s still yielding new discoveries today.

Titan, which is the only other world that we know of in our solar system that supports liquid on its surface, is well known for its colossal lakes that are filled with hydrocarbons, but it’s the towering structures on the shores of those lakes that are the subject of a new research effort published in Nature Geoscience.

Astronomers have a new theory about how some of the lakes on Saturn ’ s moon Titan formed.

In contrast to most lakes here on Earth, many of the lakes found on Titan’s surface are surrounded by steep ridges stretching hundreds of feet into the sky. Exactly how those structures formed is a question scientists are eager to answer, a new model suggests a possible explanation.

Using radar data from Cassini, scientists have built computer simulations that show how explosions of warming nitrogen within Titan’s crust could have formed such basins. It’s possible, the researchers say, that liquid nitrogen, enduring periods of cooling and heating thanks to the greenhouse effect from Titan’s atmosphere, could have heated rapidly enough that, when it vaporized, it caused an explosion in the crust and formed craters.

Saturn ' s moon Titan is home to seas and lakes filled with liquid hydrocarbons, but what forms the depressions on the surface? Recently a team of scientists turned to our home planet for the answer. They discovered that Titan 's lakes are reminiscent of what are known as karstic landforms on Earth.

In this hypothetical scenario, the craters became the perfect places for raining hydrocarbons to pool, laying the groundwork for the lakes we see covering the moon today.

“This is a completely different explanation for the steep rims around those small lakes, which has been a tremendous puzzle,” Linda Spilker of NASA’s Jet Propulsion Laboratory explains. “As scientists continue to mine the treasure trove of Cassini data, we’ll keep putting more and more pieces of the puzzle together. Over the next decades, we will come to understand the Saturn system better and better.”
