Solar System: 10 Things to Know This Week
Need some space?
Here are 10 perspective-building images for your computer desktop and mobile device wallpaper.
These are all real images, sent very recently by our planetary missions throughout the solar system.
1. Our Sun
Warm up with this view from our Solar Dynamics Observatory showing active regions on the Sun in October 2017. They were observed in a wavelength of extreme ultraviolet light that reveals plasma heated to over a million degrees.

2. Jupiter Up-Close
This series of enhanced-color images shows Jupiter up close and personal, as our Juno spacecraft performed its eighth flyby of the gas giant planet on Sept. 1, 2017.

3. Saturn’s and Its Rings
With this mosaic from Oct. 28, 2016, our Cassini spacecraft captured one of its last looks at Saturn and its main rings from a distance.

4. Gale Crater on Mars
This look from our Curiosity Mars rover includes several geological layers in Gale crater to be examined by the mission, as well as the higher reaches of Mount Sharp beyond. The redder rocks of the foreground are part of the Murray formation. Pale gray rocks in the middle distance of the right half of the image are in the Clay Unit. A band between those terrains is "Vera Rubin Ridge," where the rover is working currently. The view combines six images taken with the rover's Mast Camera (Mastcam) on Jan. 24, 2017.

5. Sliver of Saturn
Cassini peers toward a sliver of Saturn's sunlit atmosphere while the icy rings stretch across the foreground as a dark band on March 31, 2017. This view looks toward the unilluminated side of the rings from about 7 degrees below the ring plane.

6. Dwarf Planet Ceres
This image of the limb of dwarf planet Ceres shows a section of the northern hemisphere, as seen by our Dawn mission. Prominently featured is Occator Crater, home of Ceres' intriguing "bright spots." The latest research suggests that the bright material in this crater is comprised of salts left behind after a briny liquid emerged from below.

7. Martian Crater
This image from our Mars Reconnaissance Orbiter (MRO) shows a crater in the region with the most impressive known gully activity in Mars' northern hemisphere. Gullies are active in the winter due to carbon dioxide frost, but northern winters are shorter and warmer than southern winters, so there is less frost and less gully activity.

8. Dynamic Storm on Jupiter
A dynamic storm at the southern edge of Jupiter's northern polar region dominates this Jovian cloudscape, courtesy of Juno. This storm is a long-lived anticyclonic oval named North North Temperate Little Red Spot 1. Citizen scientists Gerald Eichstädt and Seán Doran processed this image using data from the JunoCam imager.

9. Rings Beyond Saturn’s Sunlit Horizon
This false-color view from the Cassini spacecraft gazes toward the rings beyond Saturn's sunlit horizon. Along the limb (the planet's edge) at left can be seen a thin, detached haze.

10. Saturn’s Ocean-Bearing Moon Enceladus
Saturn's active, ocean-bearing moon Enceladus sinks behind the giant planet in a farewell portrait from Cassini. This view of Enceladus was taken by NASA's Cassini spacecraft on Sept. 13, 2017. It is among the last images Cassini sent back before its mission came to an end on Sept. 15, after nearly 20 years in space.
