The map also reveals how the radiation is influenced by the smaller moons orbiting close to Jupiter's rings. The success of this project relies on data collected by Juno's Advanced Stellar Compass ...

More than 400 years after Galileo's discovery of Io, the innermost of Jupiter's largest moons, a team of scientists has produced the first complete global geologic map of the Jovian satellite.

Astronomers just made an extremely detailed map of the solar system's most volcanically active body, Jupiter's moon Io, thanks to a rare orbital alignment. Jupiter's third largest moon, Io sees at ...

JANUS will map the entire surface of Ganymede and, with data collected during flybys, map the surfaces of Europa and Callisto and map specific regions in high resolution. JANUS will also be used to ...

But in many ways, this flyby was just a teaser for upcoming missions—especially Europa Clipper, which is scheduled to launch in 2024 for a series of close-up orbital encounters with the icy moon ...

In 2023, NASA will send a spacecraft to a metal world, samples from an asteroid will be dropped off on Earth, the Artemis II astronauts will be selected, and several new commercial rockets could ...

Jupiter already reigns as king of the planets — it's the largest one in our solar system. And now, the gas giant has the most known moons, too.Astronomers have observed 12 additional moons ...

As the moons have orbital periods of just a few days, transits occur hundreds of times per year. At opposition Dec. 7, you can catch Io beginning to transit at 4:30 a.m. EST.

Instead, the team focused on the orbital dynamics of Jupiter's moons and the conservation of the planet's angular momentum—quantities that are directly measurable.

As of February 2024, Jupiter has 95 moons. By comparison, Mercury, and Venus are moonless , Earth has one moon, and Mars has two. Uranus and Neptune have 28 and 16 known moons, respectively.
