Juno is a NASA space probe orbiting the planet Jupiter. It was built by Lockheed Martin and is operated by NASA 's Jet Propulsion Laboratory. The spacecraft was launched from Cape Canaveral Air Force Station on August 5, 2011 UTC, as part of the New Frontiers program. [ 6 ]Juno entered a polar orbit of Jupiter on July 5, 2016, UTC, [ 4 ][ 7 ...
A montage of Jupiter and its four largest moons (distance and sizes not to scale) There are 95 moons of Jupiter with confirmed orbits as of 5 February 2024. [1] [note 1] This number does not include a number of meter-sized moonlets thought to be shed from the inner moons, nor hundreds of possible kilometer-sized outer irregular moons that were only briefly captured by telescopes. [4]
Juno also studies Jupiter's deep winds, [58] [59] which can reach speeds of 600 km/h. [60] [61] Among early results, Juno gathered information about Jovian lightning that revised earlier theories. [62] Juno provided the first views of Jupiter's north pole, as well as insights about Jupiter's aurorae, magnetic field, and atmosphere. [63]
Once every 53.5 days, NASA's Juno probe screams over Jupiter's cloud, capturing stunning images in the process. NASA's $1 billion Jupiter probe just sent back dazzling new photos of the giant ...
In both the ancient Greek and Roman civilizations, Jupiter was named after the chief god of the divine pantheon: Zeus to the Greeks and Jupiter to the Romans. [19] The International Astronomical Union formally adopted the name Jupiter for the planet in 1976 and has since named its newly discovered satellites for the god's lovers, favourites, and descendants.

On Tuesday, NASA released the first set of images from Juno's in-orbit view and as expected, they are spectacular.
Ganymede, or Jupiter III, is the largest and most massive natural satellite of Jupiter, and in the Solar System. Despite being the only moon in the Solar System with a substantial magnetic field, it is the largest Solar System object without a substantial atmosphere. Like Saturn 's largest moon Titan, it is larger than the planet Mercury, but ...
The primary observation target is Jupiter itself, although limited images of some of Jupiter's moons have been taken and more are intended. [5] JunoCam successfully returned detailed images of Ganymede after Juno's flyby on June 7, 2021, [ 6 ] with further opportunities including planned flybys of Europa on September 29, 2022, and two of Io ...
