Some of the most intriguing features visible in the new @NASAWebb Jupiter images are the giant planet's rings. @NASAVoyager scientists made the surprise discovery in 1979, and our #JunoMission even captured a view of them looking from the inside out! 1/3 A wide field view showcases Jupiter in the upper right quadr
As the Juno spacecraft zipped through the narrow gap between Jupiter's radiation belts and the planet during its first science flyby in August 2016, a star tracking camera collected this image showing the dusty rings and the stars beyond, including bright Betelgeuse. 2/3 A bright, narrow double band of dust cuts horizontally throu
Juno also captures close-ups of Jupiter from Jovian orbit. Like the @NASAWebb images released yesterday, these are often processed from raw data by #CitizenScientist members of the public, such as this one by Andrea Luck.

It's 2/2/22! For this day of 2️⃣s, here are some iconic pairs in our solar system. Some asteroids come in twos, such as Ida & Dactyl, as seen by the Galileo spacecraft. This year, our #DARTMission will perform its test at another pair, Didymos & Dimorphos: go.nasa.gov/3ofmhes an asteroid and its tiny moonlet against the blackness of sp
Two small moons of Saturn, Janus & Epimetheus, share very similar orbits around the planet, and they regularly swap positions. This series of images was captured by Cassini. go.nasa.gov/3giKM6T
Pluto and its largest moon Charon, seen here by the #NewHorizonsMission, are sometimes described as a double planet, since they orbit around the common center of gravity between them. go.nasa.gov/3giWoH0 smaller Charon and larger Pluto in space

Luck favors the prepared! The #DARTMission has lifted off to begin its journey to a double asteroid, where it will test techniques to deflect an asteroid if someday one presents a hazard to Earth. Ride along here and at nasa.gov/dart rocket lifting through clouds, setting them aglow
The #DARTMission spacecraft has separated from the @SpaceX rocket, and is on its way to the Didymos double asteroid system, where it is expected to arrive late next year. video still frame showing spacecraft against the blackness o

There was a flurry of activity on the surface of the Sun this week, including large solar flares and storms. Here, @NASASun’s Solar Dynamics Observatory in Earth orbit captured an especially active solar region on Nov. 2.
1/4
The Sun launched multiple coronal mass ejections (CMEs) that sent waves of charged particles toward Earth. The SOHO spacecraft caught one as it blasted out into the solar system.
2/4
When these particles arrived at Earth, its magnetic field directed them toward the north & south poles, where they lit up the atmosphere with auroras. These geomagnetic storms were so powerful that people far from the poles got to see the show. This view was captured in Utah. 3/4

The Juno spacecraft continues its approach on the night side of Ganymede.

Current distance to Ganymede: about 16,000 miles (26,000 kilometers).

Congratulations to the Ingenuity #MarsHelicopter team on the first powered flight on another planet!

How far could robotic rotorcraft like Ingenuity take us in space exploration? Far. Very far.

Let’s talk about titans and dragonflies. 1/4
Saturn’s moon Titan is bigger than Mercury! With a soupy atmosphere thicker than Earth's and only 1/7th the gravity, it’s the perfect place to explore with a flying rover. 2/4
The surface is loaded with enigmatic features like dunes of weird carbonaceous material and mountains of ice-rock. It even has boulders and pebbles created by liquid methane, as seen in this image from @esa's Huygens probe that landed on Titan. 3/4 photograph of rocky terrain...
