NASA's Juno probe returns close-up photographs of Ganymede, Jupiter's biggest moon, after 20 years
On Monday, NASA's Juno spacecraft flew by Jupiter's biggest moon, Ganymede. For the first time in 20 years, the Juno mission captured a close-up image of the ice-encrusted moon. NASA anticipates additional Ganymede photos in the near future, as well as data on its ice shell, which might conceal an ocean. In a news release, NASA stated, "This is the closest any spacecraft has been near this enormous moon in a generation."
