Its latest find? The […]
When NASA’s Juno spacecraft performed its closest approach to Jupiter‘s moon Europa in September 2022, it captured evidence not only for pockets of briny water connected to the world’s deep subsurface ocean, but also for potential scars formed by towering plumes of water vapor — and it caught that evidence on camera The majority of […]
Oh, there it is. Jupiter’s unassuming moon Amalthea was spotted in two recent images captured by NASA’s Juno probe. During its 59th close flyby of Jupiter on March 7, the Juno spacecraft captured its usual stunning views of the giant planet’s swirling winds and colorful belts. The new photos offered an unexpected treat: a rare […]
The four biggest moons of Jupiter aren’t just blurry smudges in Galileo’s telescope anymore. The Italian astronomer Galileo Galilei discovered Ganymede, Callisto, Europa and Io back in 1610, which explains why they’re called the Galilean moons. We’ve learned a lot about these exotic bodies in the past 400 years thanks to ever-improving telescope views and […]
NASA’s Juno spacecraft has made a second flyby of Jupiter’s moon Io, capturing the solar system’s most volcanic body in stunning detail. The spacecraft also allowed operators to glimpse a side of Io not seen in 35 years. The images of Io were taken last week, made possible by the Feb. 3 flyby that saw […]
NASA’s Juno spacecraft has now paid Jupiter’s moon Io its second close-up visit in less than two Earth months. To mark the rendezvous, NASA and the Southwest Research Institute released a new batch of images showing the infamously infernal moon in a state of seemingly uncharacteristic calm. Scientists also released a video showing Juno’s gradual […]
NASA’s Juno spacecraft made a close flyby of Jupiter’s intriguing moon Europa in 2022, revealing potential hints of present day surface activity. The spacecraft’s Stellar Reference Unit (SRU), which is a star camera designed to assist Juno’s onboard attitude determination, was used to image Europa’s surface with high resolution while being lit up by Jupiter-shine, […]
During its 57th flyby of Jupiter, NASA’s Juno spacecraft came closer to the planet’s moon Io than any other mission has in the last two decades. Passing within around 930 miles (1,500 kilometers) of Io, the most volcanic body in the solar system, on Saturday, Dec. 30, 2023, Juno was able to capture stunningly detailed […]
NASA’s Juno mission will come closer to Jupiter’s moon Io than any spacecraft has in around 20 years on Saturday (Dec. 30). The flyby will bring Juno to around 930 miles (1,500 kilometers) of Io, the most volcanic body in the solar system. This will allow the spacecraft to take a detailed look at Io […]
