Ganymede and Europa, two of Jupiter’s 80 known moons, have been photographed from Earth. The new observation revealed the sharpest images ever taken from Earth, but was largely blurred. But the purpose of the photographs was also different.
Jupiter, the largest planet in the Solar System, is in the focus of astronomers not only with its own beauty, but also with 80 different moons that have been discovered so far. Among these satellites Europa and Ganymede can come to the fore.
Jupiter’s giant moon Ganymede and its moons, known to be covered in ice, Europa have previously been photographed relatively closely with spacecraft such as Juno. This time, scientists have confirmed that these satellites the clearest photos of the ground shared.

Scientists from the University of Leicester in ChileVery Large TelescopeWith the help of ” he photographed the surfaces of the satellites and began to work on them. The photo of the two satellites was shared with the public as above.
It is quite normal for the satellites to appear blurry in the photos taken. Because NASA’s Juno spacecraft has recently managed to take the clearest pictures of these satellites. But the main purpose of these photos is not really clarity,’cosmic fingerprint‘ was to follow.
Newly taken photos from the surface of Europa and Ganymede into space amount of reflected sunlight was showing. These reflectance measurements are analyzed with a computer model and thus compared with existing reflectance measurements of known substances such as water and minerals. This allows us to study the chemical compositions in satellites from Earth.
The Juno spacecraft photographed Europa and Ganymede as follows:
