Californians woke up to an alien-looking sky this morning, Wednesday, September 9, 2020.Continue reading “Can you tell the difference between California, Venus, Titan and Mars? Hint: California is the one with buildings.”
Where did Saturn’s bizarro-moon Titan form? Did it form where it is now, or has it migrated? We have decades of data to look back on, so scientists should have some idea.
A new study based on all that data says that Titan is drifting away from Saturn more quickly than thought, and that has implications for where the moon initially formed.Continue reading “Titan is Drifting Away from Saturn Surprisingly Quickly”
Saturn’s moon Titan is alone among the Solar System’s moons. It’s the only one with any atmosphere to speak of. Other moons may have thin, largely insignificant atmospheres, like Ganymede with its potential oxygen atmosphere. But Titan’s atmosphere is dense, and rich in nitrogen.
A new study shows that Titan’s atmosphere and winds might produce dust devils similar to Earth’s.Continue reading “There Might Be Dust Devils On Titan Too”
Beyond Earth’s only satellite (the Moon), the Solar System is packed full of moons. In fact, Jupiter alone has 79 known natural satellites while Saturn has the most know moons of any astronomical body – a robust 82. For the longest time, astronomers have theorized that moons form from circumplanetary disks around a parent planet and that the moons and planet form alongside each other.
However, scientists have conducted multiple numerical simulations that have shown this theory to be flawed. What’s more, the results of these simulations are inconsistent with what we see throughout the Solar System. Thankfully, a team of Japanese researchers recently conducted a series of simulations that yielded a better model of how disks of gas and dust can form the kinds of moon systems that we see today.Continue reading “Gas and Dust Stop Planets From Eating Their Moons”
Titan’s methane-based hydrologic cycle makes it one of the Solar System’s most geologically diverse bodies. There are lakes of methane, methane rainfall, and even “snow” made of complex organic molecules. But all of that detail is hidden under the moon’s dense, hazy atmosphere.
Now a team of scientists have used data from the Cassini mission to create our first global geological map of Titan.Continue reading “Scientists Construct a Global Map of Titan’s Geology”
When it comes to space exploration, it’s robots that do most of the work. That trend will continue as we send missions onto the surfaces of worlds further and further into the Solar System. But for robots to be effective in the challenging environments we need to explore—like Saturn’s moon Titan—we need more capable robots.
A new robot NASA is developing could be the next step in robotic exploration.Continue reading “Shape-shifting Robots Like These Could Be Just What We Need to Explore Titan”
The Cassini spacecraft ended its mission to Saturn and its moons two years ago when it was sent plunging into Saturn to be destroyed. But after two years, scientists are still studying the data from the Cassini mission. A new paper based on Cassini data proposes a new explanation for how some lakes on Titan may have formed.Continue reading “Whoa. Lakes on Titan Might be the Craters from Massive Underground Explosions”
There are few places in the Solar System which are as fascinating as Saturn’s moon Titan. It’s a world with a thicker atmosphere than Earth. Where it’s so cold that it rains ammonia, forming lakes, rivers and seas. Where water ice forms mountains.
Like Europa and Encleadus, Titan could have an interior ocean of liquid water too, a place where there might be life.Continue reading “How Habitable is Titan? NASA is Sending the Titan Dragonfly Helicopter to Find Out”
Some lakes on Titan have ring-like shapes around them, and scientists are trying to find out how they formed. Understanding how they formed may tell us something about how the entire region they’re in, including the lakes, formed. The ring-shaped features are found around pools and lakes at Titan’s polar regions.Continue reading “There are Ring-Like Formations Around the Lakes on Titan”
Titan is a distant, exotic, and dangerous world. It’s frigid temperatures and hydrocarbon chemistry is like nothing else in the Solar System. Now that NASA is heading there, some researchers are getting a jump on the mission by recreating Titan’s chemistry in jars.Continue reading “A Jarful of Titan Could Teach Us A Lot About Life There, and Here On Earth”
