2022年10月3日 Jupiter’s Europa from Spacecraft Juno Image Credit & License: NASA, JPL-Caltech, SwRI, MSSS; Processing: Andrea Luck Explanation: What mysteries might be solved by peering into this crystal ball? In this case, the ball is actually a moon of Jupiter, the crystals are ice, and the moon is not only dirty but cracked beyond repair. Nevertheless, speculation is rampant that oceans exist under Europa’s fractured ice-plains that could support life. Europa, roughly the size of Earth’s Moon, is pictured here in an image taken a few days ago when the Jupiter-orbiting robotic spacecraft Juno passed within 325 kilometers of its streaked and shifting surface. Underground oceans are thought likely because Europa undergoes global flexing due to its changing gravitational attraction with Jupiter during its slightly…

The core of NASA’s Europa Clipper spacecraft has taken center stage in the Spacecraft Assembly Facility at the agency’s Jet Propulsion Laboratory in Southern California. Standing 10 feet (3 meters) high and 5 feet (1.5 meters) wide, the craft’s main body will for the next two years be the focus of attention in the facility’s ultra-hygienic High Bay 1 as engineers and technicians assemble the spacecraft for its launch to Jupiter’s moon Europa in October 2024. See more images of the spacecraft coming together.

2022年7月17日 Europa and Jupiter from Voyager 1 Image Credit: NASA, Voyager 1, JPL, Caltech; Processing & License: Alexis Tranchandon / Solaris Explanation: What are those spots on Jupiter? Largest and furthest, just right of center, is the Great Red Spot — a huge storm system that has been raging on Jupiter possibly since Giovanni Cassini’s likely notation of it 357 years ago. It is not yet known why this Great Spot is red. The spot toward the lower left is one of Jupiter’s largest moons: Europa. Images from Voyager in 1979 bolster the modern hypothesis that Europa has an underground ocean and is therefore a good place to look for extraterrestrial life. But what about the dark spot on the upper right? That is a…
