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 ...
Jupiter would deliver about 36 Sv (3600 rem) per day to unshielded astronauts at Io and about 5.4 Sv (540 rems) per day to unshielded astronauts at Europa, [89] which is a decisive aspect due to the fact that already an exposure to about 0.75 Sv over a period of a few days is enough to cause radiation poisoning, and about 5 Sv over a few days ...
Starting with Galileo's first orbit, the spacecraft's camera, the Solid-State Imager (SSI), began taking one or two images per orbit of Io while the moon was in Jupiter's shadow. This allowed Galileo to monitor high-temperature volcanic activity on Io by observing thermal emission sources across its surface. [ 68 ]
On Tuesday, NASA released the first set of images from Juno's in-orbit view and as expected, they are spectacular.
Just one day before opposition, Jupiter will be around 367 million miles away from the Earth, the closest the two planets have been in 59 years, according to NASA. The last time that Jupiter was ...
Jupiter might have shaped the Solar System on its grand tack. In planetary astronomy, the grand tack hypothesis proposes that Jupiter formed at a distance of 3.5 AU from the Sun, then migrated inward to 1.5 AU, before reversing course due to capturing Saturn in an orbital resonance, eventually halting near its current orbit at 5.2 AU.
Jupiter may be best known as the planetary titan of our solar system with a comparatively small red mark — that still dwarfs the entirety of Earth — and rows of striations going from pole to pole.
Hubble image of the scar taken on 23 July 2009 during the 2009 Jupiter impact event, showing a blemish of about 8,000 kilometres long. [1] In recorded history, the planet Jupiter has experienced impact events and has been probed and photographed by several spacecraft.
