Jupiter's volcanic moon Io looks outstanding in these close flyby photos from NASA's Juno probe

A pale brown-green planet is half shaded in the black of space.

NASA's Juno spacecraft has now paid Jupiter's moon Io its second close-up visit in less than two Earth months.

To mark the rendezvous, NASA and the Southwest Research Institute released a new batch of images showing the infamously infernal moon in a state of seemingly uncharacteristic calm. Scientists also released a video showing Juno's gradual approach to the Jovian satellite — a sphere pockmarked with points of light from volcanic eruptions.
