Jupiter has long been a source of fascination for astronomers, and now, the giant planet is raising more questions than ever.

Io, one of the most fascinating moons in our solar system, continues to mystify scientists with its intense volcanic activity ...

The new calculations, described in a paper published Tuesday (May 20) in the journal Nature Astronomy, suggest that just 3.8 ...

To better understand Jupiter’s primordial stages, researchers turned to the tiniest of the planet’s 92 known moons. Almathea and Thebe respectively circle Jupiter at slightly tilted orbits roughly 112 ...

The researchers also determined that Jupiter's magnetic field at that time was approximately 50 times stronger than it is today. Adams highlights the remarkable imprint the past has left on today ...

A recent study found that Jupiter was once twice the size that it is now, making it big enough to swallow up 2,000 Earths.

Amazing new data gathered by Juno, the NASA space probe that has been orbiting Jupiter for the past two years, revealed the gaseous giant has a unique magnetic field. Earth’s field is consistent ...

Astronomers have calculated that the gas giant Jupiter used to be twice as big as it is now, based on the odd orbits of two ...

These temporary events have been found around Earth and Mars, and now researchers report that even Jupiter has them. The biggest planet in the Solar System has a magnetic field that is 20,000 ...

New research suggests that Jupiter, the largest planet in our solar system, was once even bigger—about twice its current size—and had a magnetic field 50 times stronger than it does today. This ...

"It's astonishing that even after 4.5 billion years, enough clues remain to let us reconstruct Jupiter's physical state at the dawn of its existence," stated Fred C. Adams, professor of physics and ...
