The mysterious surface of Saturn's huge moon Titan comes into gloriously sharp focus in newly released photos captured by NASA's Cassini spacecraft.
This is a new picture of Neptune taken from the Earth. It’s nothing short of amazing.
Over the past 18 months, astronomers have painstakingly tracked a dozen tiny moons that they found circling the giant planet Jupiter.
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.
Results from computer simulations confirm that young Uranus was involved in a cataclysmic collision with an object twice the mass of Earth.
Last October, researchers spotted a long, skinny object speeding through our solar system. Additional observations have now earned the object a comet label.
Using mass spectrometry data from NASA's Cassini spacecraft, scientists found that large, carbon-rich organic molecules are ejected from cracks in the icy surface of Saturn's moon Enceladus.
A storm of tiny dust particles on Mars has prompted NASA's Opportunity rover to suspend science operations. The Martian dust storm has grown in size and is now officially a 'planet-encircling' (or 'global') dust event.
One of the thickest dust storms ever seen on Mars has been spreading since early June. The Opportunity rover - 1 of 2 active rovers on Mars - has suspended science operations.
A new analysis of data from NASA's Dawn mission suggests that organic matter may exist in surprisingly high concentrations on the dwarf planet's surface.
The finding has significant implications for whether life once existed on Mars.
Starting in early June, Dawn will begin collecting gamma ray and neutron spectra to better understand the composition of the topmost rock and soil layers while taking high-resolution photographs of dwarf planet Ceres.
The asteroid, currently nestling in Jupiter's orbit, is the first known asteroid to have been captured from another star system.
The new clue to Planet Nine's existence was spotted in data from the Dark Energy Survey. The new object we can see and observe is called 2015 BP519, and looks like it could be as big as Pluto itself.
Citing data collected by NASA's Galileo probe more than two decades ago, scientists report that giant jets of water are spouting more than 100 miles off Jupiter moon Eupora's surface.
