Cassini’s awe-inspiring view of Jupiter’s volcanic moon Io

[CLICK ON IMAGE FOR HIGH RESOLUTION, Cassini Imaging Team, SSI, JPL, ESA, NASA] How big is Jupiter’s moon Io? The most volcanic body in the Solar System, Io (usually pronounced “EYE-oh”) is 3,600 kilometers in diameter, about the size of planet Earth’s single large natural satellite. Gliding past Jupiter at the turn of the millennium, […]

‘Built like an armored tank’, Juno swoops through debris, radiation in Jupiter’s upper atmosphere

July 4, 2016 [CLICK ON IMAGE FOR HIGH RESOLUTION] NASA’s Juno spacecraft was to fire its main rocket engine late Monday to slow itself down from a speed of 150,000 mph (250,000 kph) and slip into orbit around Jupiter. With Juno on autopilot, the delicately choreographed move comes without any help from ground controllers. The […]

Juno, on July 4, will fire engine, orbit Jupiter’s poles at cloud-top level

Juno, on July 4, will fire engine, orbit Jupiter’s poles at cloud-top level

After nearly a five-year journey, Juno enjoys a perspective on Jupiter not often seen, even by spacecraft from Earth that usually swing by closer to Jupiter’s equator. Looking down toward the ruling gas giant from a distance of 10.9 million kilometers, the spacecraft’s JunoCam captured this image with Jupiter’s nightside and orbiting entourage of four […]

Jupiter’s largest moon poses with our solar system’s largest storm

[CLICK ON IMAGE FOR HIGH RESOLUTION, Damian Peach/SEN] In this sharp snapshot, the Solar System’s largest moon Ganymede poses next to Jupiter, the largest planet. Captured on March 10 with a small telescope from our fair planet Earth, the scene also includes Jupiter’s Great Red Spot, the Solar System’s largest storm. In fact, Ganymede is […]
