Where does the water on Earth come from? How was our Moon formed? And is there one single event that had led to the formation of both?
The surface of Jupiter's moon Europa features a widely varied landscape, including ridges, bands, small rounded domes and disrupted spaces that geologists call "chaos terrain."
A team of astronomers has created the first global map of Titan by using the Cassini probe's over 100 fly-bys to stitch together both imagery and radar measurements.
A team of German scientists recently examined data gathered by the Cassini orbiter around Enceladus’ southern polar region and found was evidence of organic signatures that could be the building blocks for amino acids.
Using Earth's most powerful array of radio telescopes, astronomers have made the first observations of a circumplanetary disk of gas and dust like the one that is believed to have birthed the moons of Jupiter.
A mysterious large mass of material has been discovered beneath the largest crater in our solar system - the Moon's South Pole - Aitken basin and may contain metal from the asteroid that crashed into the Moon and formed the crater.
Researchers determined hydrocarbons can form the type of complex chains that create Titan's orange-brown haze layers at temperatures as low as 330 degrees below freezing on Earth.
The mysterious surface of Saturn's huge moon Titan comes into gloriously sharp focus in newly released photos captured by NASA's Cassini spacecraft.
In its quest to find extant life in the Solar System, NASA has focused its gaze on the Jovian moon Europa. But scientists believe it is Enceladus that stands the greatest chance of making that next big step.
