How old is the Moon? Astronaut-gathered samples from the lunar surface put its age at about 4.35 billion years. However, ...

We knew data from Juno’s two very close flybys could give us some insights on how this tortured moon actually worked.” Io orbits around Jupiter, the largest planet in our solar system ...

No moon in our solar system is likely as chaotic as Io, Jupiter’s third largest. The rocky body looks like a pepperoni pizza because of the constant, numerous eruptions on its surface.

Jupiter's volcanic moon Io doesn't appear to have a subsurface ocean of magma, resolving some issues about how Io's volcanoes erupt and raising broader questions about similar magma oceans within ...

This process is called "tidal heating." It is how Jupiter currently heats up its moon Io, the most volcanically active spot in the solar system. Sponsor Message "We think that the Moon went ...

Only Jupiter's moon Io, by far the most volcanically active body in the solar system, offers comparable conditions. These new considerations published today in the journal Nature by an ...

In 1979, NASA Jet Propulsion Laboratory (JPL) scientist Linda Morabito discovered volcanic activity on Jupiter’s innermost moon, Io. But Io isn’t just volcanically active—it is the most ...

The discovery solves a 44-year-old mystery of why, and how, Jupiter's violent moon, Io, became so volcanically active. Io is only slightly larger than our moon, with a diameter of 2,237 miles ...

Early interactions with the Earth may have heated up the Moon and caused it to remelt, producing new lunar rocks and erasing old craters.
