Jupiter - NASA Science
WEBJupiter also is the oldest planet, forming from the dust and gases left over from the Sun's formation 4.5 billion years ago. But it has the shortest day in the solar system, taking only 10.5 hours to spin around once on its axis. NASA’s Juno spacecraft took three images of Jupiter’s Great Red Spot on Feb. 12, 2019, that were used to create ...
Saturn - NASA Science
WEBSaturn is a massive ball made mostly of hydrogen and helium. The farthest planet from Earth discovered by the unaided human eye, Saturn has been known since ancient times. The planet is named for the Roman god of agriculture and wealth, who was also the father of Jupiter. NASA's Cassini spacecraft took this image of Saturn on Feb. 9, 2004, when ...
Solar System Exploration - NASA Science
WEBOur solar system orbits the center of the galaxy at about 515,000 mph (828,000 kph). It takes about 230 million years to complete one orbit around the galactic center. We call it the solar system because it is made up of our star, the Sun, and everything bound to …
What Is Climate Change? - NASA Science
WEBClimate change is a long-term change in the average weather patterns that have come to define Earth’s local, regional and global climates. These changes have a broad range of observed effects that are synonymous with the term. Changes observed in Earth’s climate since the mid-20th century are driven by human activities, particularly fossil fuel burning, […]

Mars Facts - Science@NASA
WEBMars has a dense core at its center between 930 and 1,300 miles (1,500 to 2,100 kilometers) in radius. It's made of iron, nickel, and sulfur. Surrounding the core is a rocky mantle between 770 and 1,170 miles (1,240 to 1,880 kilometers) thick, and above that, a crust made of iron, magnesium, aluminum, calcium, and potassium.

Climate Change - NASA Science
WEBThe Ocean and Climate Change. Our ocean is changing. With 70 percent of the planet covered in water, the seas are important drivers of the global climate. Yet increasing greenhouse gases from human activities are altering the ocean before our eyes. NASA and its partners are on a mission to find out more.
