International team of scientists have discovered the unusual evolution of the central star of a planetary nebula in our Milky Way. This extraordinary discovery sheds light on the ultimate fate of the sun.
The US space agency launches a probe that aims to travel closer to the Sun than ever before.
This summer, humanity embarks on its first mission to touch the Sun: A spacecraft will be launched into the Sun's outer atmosphere.
A new analysis of 15 years of data from the Mars Express probe by a team of Italian scientists shows compelling evidence for their being liquid water beneath Mars southern polar region.
The ESA recently released stunning photos of a Martian storm front, which were acquired by the Mars Express orbiter in April of 2018.
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.
