Stargazers in the U.S. will see Jupiter rise above the eastern horizon roughly two hours before sunrise on Aug. 8, with Venus visible as a bright morning "star" less than 5 degree ...

ESA's Mars Express orbiter captured footage of the Mars' moon Deimos pass in front of Ganymede, Europa, Jupiter, Io and ...

The mutilated surface of Jupiter’s moon Io was revealed in great detail by the Juno spacecraft, which has been exploring the Jovian system since 2016 and recently pulled off the closest flyby of ...

Because Io is so close to its massive host planet, the moon is subjected to a tremendous gravitational pull as it orbits Jupiter once about every 42 hours, according to the Planetary Society.

NASA’s Galileo spacecraft image of Io from July 1999 (main) and infrared data collected Oct. 15, 2023, by the JIRAM instrument aboard NASA’s Juno showing Chors Patera, a lava lake on Jupiter ...

Jupiter’s moon Io may have been volcanically active throughout its life. In this image of Io, taken by NASA’s Juno spacecraft in 2023, a bright volcanic plume can be seen on the left, just ...

The volcano-pocked surface of Jupiter’s moon Io was captured in infrared by the Juno spacecraft’s Jovian Infrared Auroral Mapper (JIRAM) imager as it flew by at a distance of about 50,000 ...

A NASA spacecraft made its closest-ever approach to Jupiter's moon Io, coming within 930 miles of the "surface of the most volcanic world," and the space agency released new images of the flyby.

That mission also extends to Jupiter's rings and many moons. In December, Juno came within about 930 miles of Io's surface – equal the distance from New York City to Orlando, Florida.

Jupiter's moon Io is one of Jupiter’s several moons. This image was taken on December 30, 2023 during the Juno spacecraft’s flyby of this volcanic Jupiterian moon.

NASA's robotic Juno spacecraft is delivering the fresh data on Io with a series of flybys, each getting closer to Jupiter's volcanic moon until a pair of close-up encounters at a range of less ...

There are new, high-quality images of Jupiter's moon, Io, thanks to the nearest flyby of the celestial body by a spacecraft in decades. NASA released images Saturday taken by the Juno spacecraft ...
