“This is a view of a ~2,000-km-wide vortex of swirling clouds above Saturn's north pole, imaged in polarized light with Cassini's narrow-angle camera on November 27, 2012. I've processed the original monochrome image to approximate the color of the area at the time.” — Jason Major
Europa Seen by Juno
Citizen scientist Björn Jónsson processed the image to enhance the color and contrast.

Ganymede from Juno
Some incredibly sharp images from the Juno mission of Ganymede. The first new views of this beautiful moon since Galileo. See more from kevinmgill on flickr. Also see the thread building up to these full composites in unmannedspaceflight.com.

Kind of Cool Image of Io from Juno
The brightest spot is a radiation signature, but all the rest are thought to be active volcanos on the Io surface. The moons are not a primary target of the Juno mission, but they do occasionally take a peek to try and monitor such phenomenon at Io. Later when the mission is extended, Juno will explore the full Jupiter system with its rings and moons. Multiple rendezvous are planned for Ganymede, Europa, and Io.
Image is not visible light, but taken with an x-ray camera.
OSIRIS-REX Leaves Bennu

A Drop Shadow of Jovian Proportions
“Io's shadow from @NASAJuno image PJ22_26 obtained on September 12, 2019. This is an approximately true color/contrast image. Jupiter's bluish sky is faintly visible at the limb.” — Björn Jónsson (image processor). Original tweet.
Asteroid Bennu Is Active?!
Take a look at this image of Bennu and notice the material being ejected from the surface in the middle of the image. We are seeing an extremely rare “active” asteroid for the first time up-close. According to Dante Lauretta of the University of Arizona, "probably the biggest surprise of the early stages of the OSIRIS-REx mission and, I would say, one of the biggest surprises of my scientific career".
Since Osiris-Rex’s arrival in January this kind of event has been observed at least eleven times with three of events ejecting over 100 observable particles. There is no official theory as to the cause, but they suggest that these particles ultimately go into orbit for a spell and eventually return to the surface of Bennu. Which explains why after billions of years the rock hasn’t whittled away to nothing.
