Cassini Spies "Unusual" Red Arcs on Saturn's Icy Moon Tethys
Cassini Reveals Unusual Red Arcs on Saturn’s Moon Tethys - Unusual arc-shaped, reddish streaks cut across the surface of Saturn’s ice-rich moon Tethys in this enhanced-color mosaic. The red streaks are narrow, curved lines on the moon’s surface, only a few miles (or kilometers) wide but several hundred miles (or kilometers) long. The red streaks are among the most unusual color features on Saturn’s moons to be revealed by Cassini’s cameras. Credits: NASA/JPL-Caltech/Space Science Institute
Saturn’s moon Iapetus photographed by the Cassini spacecraft. The right side is overexposed because it’s illuminated by the Sun. The left side glows by light reflecting off Saturn’s clouds. Since sunlight is much fainter at Saturn’s distance than at Earth’s, Cassini had to make a long time exposure to capture this image. (Credit: NASA) Mona Evans, "Earthshine" www.bellaonline.c...

#Astronomy: The facts about #Titan's heavy atmosphere, lakes of hydrocarbons and the possibility of life. Discovered in the year 1655, Titan is the largest of Saturn’s 62 charted moons. Titan is the only moon in the solar system with a dense atmosphere and stable bodies of liquid on its surface. The environment on Titan is deadly to human life, with a toxic atmosphere consisting mostly of nitrogen and methane. The surface temperature is minus 290 degrees F (minus 179 degrees C). #Infographic

False-color image of Europa's trailing northern hemisphere. (Credit: NASA/JPL/University of Arizona) A geological survey of Europa showed a massive, 20,000 square-km portion of its surface was gone. In Sept 2014, researchers published evidence suggesting a plate tectonic system may be moving old portions of the surface beneath adjacent plates. If confirmed, this would make Europa the only known place in the solar system (apart from Earth) whose surface is being shaped by active plate tectonics.

Evidence For Icy Plate Tectonics Found On Europa - Geology, Astronomy
New Finding: Europa Might Have Plate Tectonics From a geological (and maybe even an environmental) standpoint, as we’ve explored the solar system, we have learned that Earth isn’t incredibly special. Yes, it is the place we call home, but we’ve found that other bodies in the solar system have weather, surfaces, and geology similar to ours. To date, Earth’s plate tectonics have remained unique, but that might not be the case anymore.

Saturn's moon Hyperion: A Moon with Odd Craters
Saturn’s sponge-like moon Hyperion. Hyperion is shaped a bit like a potato and, with dimensions of 410 x 260 x 220 km, is one of the largest bodies in the Solar System known to be so irregular. Its odd, almost ‘bubbly’ appearance, can be attributed to it having a very low density for its size. Because of these properties the entire moon is porous, like a sponge, with well-preserved craters of all shapes and sizes packed together across its surface. Scientists think that this moon is mostly made up of water ice, with small amounts of rock. Photo made by Cassini in 2005. NASA/JPL/Space Science Institute

Global View of Iapetus' Dichotomy These two global images of Iapetus show the extreme brightness dichotomy on the surface of this peculiar Saturnian moon. While low and mid latitudes of the leading side exhibit a surface almost as dark as charcoal, broad tracts of the trailing side are almost as bright as snow. The dark terrain covers about 40 percent of the surface and is named Cassini Regio. The bright terrain is Roncevaux Terra (north) and Saragossa Terra (south).

Is there anywhere in the solar system that we know you could go for a nice dip? Saturn's hazy moon Titan is one. The frozen world is too far from the sun to have liquid water on its surface. But temperatures are just right for hydrocarbons like methane and ethane to flow, creating enormous seas like this one, Ligeia Mare.

Titan's upper atmosphere (natural color). Here methane molecules are broken apart by solar UV light and the byproducts combine to form compounds like ethane and acetylene. The haze preferentially scatters blue and UV wavelengths of light. Lower in the atmosphere, the haze turns into a smog of complex organic molecules that absorbs about 90% of the visible light from the Sun.
