Jupiter's Great Red Spot, the massive anticyclonic storm that churns across the planet's surface, may be shrinking. Using new NASA/ESA Hubble Space Telescope images, scientists have captured the Red Spot at its smallest size to date.
NASA scientists are learning a bit more about the largest moon in our solar system, Ganymede. They've discovered that Jupiter's moon may have ice and oceans stacked up in several layers like a club sandwich.
As reported yesterday, the White House released NASA’s 2015 base budget proposal. It contained $17.5 billion in needed funds to cover various aspects of the space program, including a $15 million mission to Jupiter’s ice moon, Europa.
NASA's Hubble Space Telescope has made some surprising discoveries when it comes to Jupiter's moon, Europa. It's spotted water vapor above the moon's frigid south polar region, providing the first strong evidence of water plumes erupting off the moon's surface.
Before it reaches its destination, Juno will greet the Earth one last time. The spacecraft will perform a flyby Oct. 9, passing within 347 miles of Earth.
In the main belt between Mars and Jupiter, families of asteroids spin through space. Now, researchers have used NASA's Wide-field Infrared Survey Explorer (WISE) to make some new finds about these objects.
If you look up at the sky tonight, you may be in for a spectacular treat. A celestial dance between three different planets will occur on Friday and into the weekend. The triple conjunction will include Venus, Jupiter and Mercury--and should make for some great sky gazing.
Water has been seen in Jupiter's stratosphere before, and now researchers know where it came from. A massive comet smashed into the surface helped ferry the water to the giant planet.
The volcanoes on Jupiter's moon, Io, are in the wrong place, baffling researchers at NASA.
Underground oceans on Jupiter's icy moon, Europa, is bubbling to the surface and it's also comprised of salty water like planet earth, making it the next perfect place to look for existence of life.
Jupiter’s icy moons will be explored in more detail by Europe’s next large science mission, JUICE, which will carry a total of 11 scientific instruments to study both the gas giant planet and its large ocean-bearing moons, as finalized and announced by ESA today.
