Who knows what happens there every time night falls?

"Juno" Jupiter probe recently sent back a surface photo of Europa (Europa, Europa ) with extremely rich details. The ice surface taken in the
photo is 150 kilometers wide and 200 kilometers long, showing many interlaced ice ridges and grooves. There are some strange features on Europa's ice, such as the notes-like patches in the lower right, which may be material gushing out of the ocean inside Europa.
photo was taken during the close flight of Euro on September 29. Its flight speed was as high as 24 kilometers per second and only 412 kilometers away from Europa's ice surface. The resolution of the photos it took reached 256 to 340 meters per pixel.
The one who took this photo was not the famous "Juno Camera", but the "Steer Reference Unit Camera" used to sense and maintain the detector's posture. The camera uses the position of the stars to determine the location of the detector by photographing the starry sky. But during this flight, it was taken as a scientific research equipment and this black and white photo was taken.
Interestingly, this photo was taken in the dark. At that time, the area taken by the photo was night, and the only light source was the sunlight reflected from the top of Jupiter's cloud. Low-light shooting is what the "Star Reference Unit Camera" is good at. It has also photographed the dim rings of Jupiter and the shallow lightning in Jupiter's atmosphere. Being able to take this photo also shows how strong the reflected light of Jupiter is.
Europa is a very interesting satellite . Scientists suspect that there may be organisms, at least microorganisms, in the oceans inside it. Although the Europa ice surface exposed to the strong radiation environment around Jupiter, the possibility of organisms appearing unlikely. But who knows what happens on the surface of the planet "Europa" whenever night falls? The relatively complete Europa photo taken by the "Juno" detector during the same flight. This photo shows the sunset of Europa. The richness of details after treatment is equally amazing. NASA / JPL-Caltech / SwRI / MSSS / Björn Jónsson
