Titan’s Lakes May Have Shoreline Erosion

Titan’s Lakes May Have Shoreline Erosion

Image Credit: Cassini Mission Here on Earth we often talk about planetary analogues. These are areas where the landscape here on our planet is geological similar to other worlds. There are regions in the Atacama desert, for instance, that are very similar to Mars.  Today, as researchers look back at Cassini data of Saturn’s moon Titan, researchers can imagine Earth analogue landscapes, where methane/ethane seas erode away their their shores in much the same way water waves here erode shorelines on Earth. In a new paper in Science Advances researchers led by Rose Palermo use simulations to...

Lava Lakes on Io Images in Infrared

I don’t think there is an astronomer who doesn’t love a pretty high resolution image of …well… pretty much anything in space. Give me a crisp clear galaxy, or a nebula, or even a quiet frost field on another planet and I will happily stare at the pretty picture. But...

Mars Rover Finds Way To Ford Ancient River

a map of Percy's path The Perseverance rover has been making its way along the coast line of a long dried up river that once allowed water to drain from Jezero Crater.  Today, the Neretva Vallis river channel isn’t just dry, it’s filled with sand dunes… And Sand Dunes...

Calculating Pluto’s Oceans

Calculating Pluto’s Oceans

While amazing data is the start of amazing research, it takes a lot of calculations and models to truly understand what the data mean.  Nine years after the New Horizons mission flew past Pluto and discovered it has mountains of ice, and a strangely cracked landscape,...

Lucy’s Discovered Dinkinesh Throws Rocks

We often find ourselves saying that science moves at that rate of technology. With new telescopes and spacecraft we can get new views on the universe. And some of them are weirdly unexpected. Back in November 2023, the Lucy mission flew past the asteroid Dinkinesh on...
